Larry Di Rita, a special assistant to Defense Secretary Donald Rumsfeld, has sent a note to Rumsfeld to inform him of the first plane hitting the World Trade Center. Although some initial reports suggest the WTC may have been hit by just a small plane, according to Victoria Clarke, the assistant secretary of defense for public affairs, “Even in the accidental crash scenario, the military might be involved in some way. Rumsfeld needed to know.” Rumsfeld, who is currently hosting a breakfast meeting with several members of Congress (see (8:00 a.m.-8:50 a.m.) September 11, 2001), later acknowledges having received this note. Yet apparently he does nothing in response. He recalls, “Everyone assumed it was an accident, the way it was described.” He says only that “we adjourned the meeting, and I went in to get my CIA briefing.” [US Department of Defense, 12/5/2001; 9/11 Commission, 3/23/2004; Clarke, 2006, pp. 217-218; Vogel, 2007, pp. 428]
Shortly After 9:03 a.m. September 11, 2001: Pentagon’s Executive Support Center Goes into Operation, But Rumsfeld Not Present
Just minutes after the second plane hits the World Trade Center, the Executive Support Center (ESC) within the Pentagon goes into operation. The ESC is located next door to the National Military Command Center (NMCC), and comprises several conference rooms that are secure against electronic eavesdropping. The Pentagon’s state-of-the-art communications hub, “Cables,” is establishing secure two-way video links with the White House and other key agencies. Assistant Secretary of Defense for Public Affairs Victoria Clarke arrives at the ESC soon after the second crash, accompanied by Larry Di Rita, who is Donald Rumsfeld’s personal chief of staff. They have just visited Rumsfeld and informed him of the second crash, but he has remained in his office to wait for his daily intelligence briefing (see (Shortly After 9:03 a.m.) September 11, 2001). Also at the ESC at this time is Rumsfeld’s closest aide, Stephen Cambone. According to Clarke, the ESC is “the place where the building’s top leadership goes to coordinate military operations during national emergencies.” Yet supposedly the Secretary of Defense does not join them there until about 10:15 A.M. (see (10:00 a.m.-10:30 a.m.) September 11, 2001). [Clarke, 2006, pp. 218-221; Cockburn, 2007, pp. 5-6]
Between 9:04 a.m. and 9:36 a.m. September 11, 2001: Defense Secretary Rumsfeld Ignores His Aides’ Attempts to Get Him to Respond to the Attacks
Victoria Clarke, the assistant secretary of defense for public affairs, and Larry Di Rita, a special assistant to the secretary of defense, try to persuade Secretary of Defense Donald Rumsfeld to cancel his schedule so he can respond to the terrorist attacks, but Rumsfeld refuses to do so and continues with a routine intelligence briefing. [Clarke, 2006, pp. 218-219; Priess, 2016, pp. 244] Rumsfeld is in his office at the Pentagon with Denny Watson, a CIA analyst, who is giving him his daily intelligence briefing. He is aware of the two crashes at the World Trade Center (see Shortly After 8:46 a.m. September 11, 2001 and (Shortly After 9:03 a.m.) September 11, 2001). [9/11 Commission, 3/23/2004; 9/11 Commission, 7/24/2004, pp. 37; Rumsfeld, 2011, pp. 334-335]
Aides Go to Talk with Rumsfeld about His Response to the Crisis – Clarke and Di Rita, meanwhile, learned of the attacks on the WTC from seeing the coverage of them on television. After the second crash, Clarke headed to Di Rita’s office, which is down the hallway from Rumsfeld’s office. There, she and Di Rita discussed “what had to be done right away in terms of the secretary [of defense],” Clarke will later recall. The two aides then headed together to see Rumsfeld, to talk with him about “the kinds of things he needed to do in response to this [crisis].”
Aides Tell Rumsfeld What They Know about the Attacks – After they enter Rumsfeld’s office, Clarke and Di Rita tell the secretary of defense what is happening and what they know about the attacks. They say the Executive Support Center (ESC) “is going to start getting spun up.” [Historical Office, Office of the Secretary of Defense, 6/27/2002 
; Historical Office, Office of the Secretary of Defense, 7/2/2002 ; Clarke, 2006, pp. 216-219] The ESC is a secure communications hub with a video teleconference facility, located on the third floor of the Pentagon. [Historical Office, Office of the Secretary of Defense, 6/27/2002 ; Vogel, 2007, pp. 440] It is “the place where the building’s top leadership goes to coordinate military operations during national emergencies,” according to Clarke.
Rumsfeld Refuses to Change His Schedule – Clarke and Di Rita also advise Rumsfeld to cancel his appointments for the rest of the day. “Sir, I think your entire schedule is going to be different today,” Di Rita says. But Rumsfeld refuses to do so. “No! If I cancel my day, the terrorists have won,” he says. Undeterred, the two aides pull out a copy of Rumsfeld’s agenda for the day and go through it point by point, explaining to the secretary of defense why each item could be canceled. However, Rumsfeld’s response is to look at the television on the desk and watch the coverage of the attacks on the WTC. [Clarke, 2006, pp. 219; Priess, 2016, pp. 244] Rumsfeld “wanted to make a few phone calls” at this time, Clarke will tell one interviewer. [WBZ Radio 1030 (Boston), 9/15/2001]
Aides Go to the Support Center to Respond to the Attacks – Rumsfeld tells the two aides to go to the ESC and wait for him there. Clarke and Di Rita therefore leave the office and head to the ESC (see Shortly After 9:03 a.m. September 11, 2001). They will be in the ESC at 9:37 a.m., when the Pentagon is attacked (see 9:37 a.m. September 11, 2001). [Historical Office, Office of the Secretary of Defense, 7/2/2002 ; Clarke, 2006, pp. 219-220] Rumsfeld, meanwhile, continues skimming through the copy of the President’s Daily Brief that Watson brought him. [Priess, 2016, pp. 244] He will still be in his office receiving his intelligence briefing when the Pentagon is attacked (see 9:37 a.m. September 11, 2001). [Goldberg et al., 2007, pp. 130; Vogel, 2007, pp. 438-439]
Shortly Before 9:37 a.m. September 11, 2001: Senior Officials Reject the Possibility of Evacuating the Pentagon
Senior officials in the Executive Support Center (ESC) at the Pentagon decide against evacuating the Pentagon, despite being aware of the attacks on the World Trade Center. [Historical Office, Office of the Secretary of Defense, 7/2/2002 ; Eichenwald, 2012, pp. 22] The ESC, on the third floor of the Pentagon, is “the place where the building’s top leadership goes to coordinate military operations during national emergencies,” according to Victoria Clarke, assistant secretary of defense for public affairs. [Clarke, 2006, pp. 219] Those currently in it include Clarke; Larry Di Rita, Defense Secretary Donald Rumsfeld’s special assistant; Stephen Cambone, principal deputy undersecretary of defense for policy; and William Haynes, the general counsel of the Department of Defense.
Officials Discuss How to Respond to the Attacks – These officials know about the two crashes in New York and realize America is under attack. They are “talking about setting up a crisis action team and how we needed to respond to this apparent terrorist attack in New York City,” Haynes will later recall. They discuss things like, “Should we think about the force conditions [and] threat conditions?” according to Di Rita. [Historical Office, Office of the Secretary of Defense, 6/27/2002 ; Historical Office, Office of the Secretary of Defense, 7/2/2002 ; Historical Office, Office of the Secretary of Defense, 7/8/2002 ; Historical Office, Office of the Secretary of Defense, 4/8/2003 ] However, they reportedly dismiss the possibility of evacuating their building. “The idea of evacuating the Pentagon was batted about, then rejected,” journalist and author Kurt Eichenwald will write. [Eichenwald, 2012, pp. 22]
Two of the Officials Thought the Pentagon Might Be a Target – This is despite the fact that at least two of them have considered the possibility of the Pentagon being attacked. Haynes has spoken to David O. “Doc” Cooke, the Pentagon’s director of administration and management, and, he will recall, told him “that we ought to be thinking about the possibility of attacks here [at the Pentagon].” [Historical Office, Office of the Secretary of Defense, 4/8/2003 ] And Cambone has talked to Vice Admiral Edmund Giambastiani Jr., Rumsfeld’s senior military assistant, about the possibility of the Pentagon being a target and what they would do if it was attacked (see Between 9:03 a.m. and 9:35 a.m. September 11, 2001). [Historical Office, Office of the Secretary of Defense, 7/8/2002 ; American Forces Press Service, 9/8/2006] Clarke and Di Rita, however, will subsequently be unclear about whether they thought the Pentagon might be attacked. When asked, “Was there any anticipation at that time that the Pentagon also might be at risk?” Clarke will only say, “There was anticipation that lots of things might be at risk.” [Historical Office, Office of the Secretary of Defense, 7/2/2002 ] And when he is asked, “At that point was there a reason to expect a larger threat specific to the Pentagon?” Di Rita will reply, “I don’t know that I thought about that.” [Historical Office, Office of the Secretary of Defense, 6/27/2002 ]
Official Will Order an Evacuation after the Pentagon Is Hit – No steps are taken to evacuate the Pentagon before it is attacked (see Before 9:37 a.m. September 11, 2001). [Newsday, 9/23/2001; Vogel, 2007, pp. 429] Cambone will finally give the order for the building to be evacuated shortly after 9:37 a.m., when the attack occurs (see 9:37 a.m. September 11, 2001). Those in the ESC will feel and hear the impact (see 9:37 a.m. September 11, 2001). Someone will then come in and report to them that the building has been hit by an airplane. “At that moment, I asked for the building to be evacuated and also locked down,” Cambone will recall. [Historical Office, Office of the Secretary of Defense, 7/8/2002 ; Clarke, 2006, pp. 220]
9:37 a.m. September 11, 2001: Pentagon’s ‘War Room’ Doesn’t Realize Building Has Been Hit, Despite Hearing Explosion
Those inside the Pentagon’s Executive Support Center (ESC) feel and hear the impact when the building is hit, yet supposedly do not realize what has happened. Victoria Clarke, the assistant secretary of defense for public affairs, who is in the ESC at this time, calls the center “the Pentagon’s war room, with instant access to satellite images and intelligence sources peering into every corner of the globe.” She describes it as “the place where the building’s top leadership goes to coordinate military operations during national emergencies.” In it with her are Stephen Cambone, Donald Rumsfeld’s closest aide, and Larry Di Rita, Rumsfeld’s personal chief of staff. They’d been discussing how to go about getting every plane currently in the air back on the ground when, according to Clarke, “we felt a jarring thump and heard a loud but still muffled explosion. The building seemed to have shifted.” Yet, despite all the ESC’s resources, they supposedly do not initially realize exactly what has happened. Clarke says to the others, “It must have been a car bomb.” Di Rita replies, “A bomb of some kind.” But one unnamed staffer who frequently uses the ESC for meetings points to the ceiling and says, “No, it’s just the heating and cooling system. It makes that noise all the time.” Clarke later claims, “The notion of a jetliner attacking the Pentagon was exactly that unfathomable back then. Our eyes were glued to television screens showing two hijacked planes destroying the World Trade Center and it still didn’t occur to any of us, certainly not me, that one might have just hit our own building.” Clarke guesses aloud that the noise was something other than the heating and cooling system. In the ensuing minutes, she and the others with her will scramble “for information about what exactly had happened, how many were hurt or killed, and [analyze] what we could do to prevent further attacks.” Yet, she will later claim, it is only when Donald Rumsfeld comes into the ESC at 10:15 a.m., after having gone to the crash scene, that they receive their first confirmation that a plane has hit the Pentagon (see (10:00 a.m.-10:30 a.m.) September 11, 2001). [Clarke, 2006, pp. 219-221] Those inside the National Military Command Center (NMCC), located next door to the ESC, supposedly do not feel the impact when the Pentagon is hit, and one officer there claims he only learns of the attack from television reports (see Shortly After 9:37 a.m. September 11, 2001). [CNN, 9/4/2002; American Forces Press Service, 9/7/2006; Cockburn, 2007, pp. 5] But Secretary of Defense Rumsfeld, who is in his office about 200 feet away from the ESC, feels the building shake due to the explosion. After seeing nothing out of his window, he immediately dashes outside to determine what has happened (see 9:38 a.m. September 11, 2001). [WBZ Radio 1030 (Boston), 9/15/2001; Parade, 10/12/2001; Washington Post, 1/9/2002; 9/11 Commission, 3/23/2004 ]
10:00 a.m.-10:30 a.m. September 11, 2001: Defense Secretary Rumsfeld Returns to the Pentagon; Speaks to President Bush and Temporarily Joins White House Teleconference
Defense Secretary Donald Rumsfeld returns from the Pentagon crash site “by shortly before or after 10:00 a.m.” Then he has “one or more calls in my office, one of which was with the president,” according to his testimony before the 9/11 Commission. [9/11 Commission, 3/23/2004 ] The commission later concludes that Rumsfeld’s call with President Bush has little impact: “No one can recall any content beyond a general request to alert forces.” The possibility of shooting down hijacked planes is not mentioned. [9/11 Commission, 6/17/2004 ] Rumsfeld then goes to the Executive Support Center (ESC) located near his office, arriving there at around 10:15 a.m. In the ESC already are Stephen Cambone, Rumsfeld’s closest aide, Larry Di Rita, Rumsfeld’s personal chief of staff, and Victoria Clarke, the assistant secretary of defense for public affairs. Rumsfeld had instructed Di Rita and Clarke to go to the ESC and wait for him there when they’d come to his office soon after the second WTC tower was hit at 9:03 A.M. (see (Shortly After 9:03 a.m.) September 11, 2001). Presently, Rumsfeld gives them their first confirmation that a plane hit the Pentagon, saying, “I’m quite sure it was a plane and I’m pretty sure it’s a large plane.” According to Clarke, he pulls out a yellow legal pad and writes down three categories, “by which his thinking would be organized the rest of the day: what we needed to do immediately, what would have to be underway quickly, and what the military response would be.” [Clarke, 2006, pp. 221-222; Cockburn, 2007, pp. 5-6] The Executive Support Center has secure video facilities, and while there, Rumsfeld participates in the White House video teleconference. This is the video conference that counterterrorism “tsar” Richard Clarke claims Rumsfeld is a part of much of the morning (see (9:10 a.m.) September 11, 2001). Then at around 10:30 a.m., he moves on to the National Military Command Center NMCC, located next door to the ESC (see (10:30 a.m.) September 11, 2001). [Washington Times, 2/23/2004; 9/11 Commission, 6/17/2004; 9/11 Commission, 7/24/2004, pp. 43-44] Those in the NMCC are apparently unaware of Rumsfeld’s whereabouts during the half-hour from 10 a.m. to 10:30 a.m.: Brigadier General Montague Winfield later recalls, “For 30 minutes we couldn’t find him. And just as we began to worry, he walked into the door of the [NMCC].” [ABC News, 9/11/2002]
6:30 p.m. September 11, 2001: Deputies Committee Holds a Teleconference to Discuss the US Response to the Attacks
The Deputies Committee of the National Security Council holds a secure video teleconference in which its members discuss how the US should respond to today’s terrorist attacks. [Myers and McConnell, 2009, pp. 160-161] The Deputies Committee is the senior sub-Cabinet interagency forum for consideration of policy issues that affect the national security interests of the United States. It is convened and chaired by the deputy national security adviser. [White House, 1/28/2017 ] The secure video teleconference is intended to prepare for a meeting of the National Security Council that will be held in the White House Situation Room tomorrow. Its participants include General Richard Myers, vice chairman of the Joint Chiefs of Staff, at the Pentagon; Deputy National Security Adviser Stephen Hadley, at the White House; Deputy Secretary of State Richard Armitage, at the State Department; and several representatives of the intelligence community, speaking from their offices. [Myers and McConnell, 2009, pp. 160]
Committee Confirms that Decontamination Units Have Been Deployed – Earlier today, Myers ordered that special decontamination units be positioned outside Washington, DC, and New York (see (Before 12:00 p.m.) September 11, 2001). [George C. Marshall European Center for Security Studies, 8/3/2012] Now, during the teleconference, it is “verified that counter-NBC [nuclear, biological, or chemical] decontamination units had been called out and deployed, standing by in case al-Qaeda decided to follow up with [weapons of mass destruction] attacks on our cities,” Myers will later recall.
Potential Targets Are Considered – Then, since President Bush has given the order to find and destroy those responsible for today’s attacks, the teleconference participants discuss potential targets to strike when the US retaliates. “We did not want a repeat of August 1998 after the al-Qaeda bombing of our embassies in Kenya and Tanzania” (see 10:35-10:39 a.m., August 7, 1998), Myers will comment. [Myers and McConnell, 2009, pp. 160] On that occasion, America responded to the bombings by firing cruise missiles at suspected terrorist camps in Afghanistan and a pharmaceutical plant in Sudan that US intelligence had identified as a chemical weapons facility (see August 20, 1998). [Washington Post, 8/21/1998; Newsweek, 8/30/1998] This response “had done little significant damage and obviously nothing to deter the terrorists,” Myers will note. The response to today’s attacks, therefore, “had to be more proportionate and, most important, more effective.”
Deputy Defense Secretary Calls Attacks ‘an Act of War’ – Deputy Secretary of Defense Paul Wolfowitz offers his opinion on today’s attacks. “This is an act of war,” he says. Talking slowly and emphasizing each word, he adds, “And… we… are… at… war.” CIA Deputy Director John McLaughlin then talks about how America should respond. “After today, we need to see clearly who is with us and who is not with us,” he says. What he means, Myers will explain, is that “Afghanistan, al-Qaeda’s home base, would not be an easy target,” since the “landlocked country had vast deserts and high, trackless mountains bisected by steep gorges.” The committee’s discussion “swirled around potential allies and enemies in the region, and how the attacks on our soil had changed the calculus of these relationships,” Myers will describe. Wolfowitz then opines, “We should be thinking whether we should declare war and then against whom?” Armitage asks, “Well, what should our declaratory policy be?”
Draft Presidential Directive Is Discussed – The Deputies Committee then discusses the draft National Security Presidential Directive on combating terrorism that was presented on September 4 (see September 4, 2001). [Myers and McConnell, 2009, pp. 160-161] The committee worked on this throughout the summer. [9/11 Commission, 7/24/2004, pp. 326] The “principal objective” of the draft directive, according to Myers, is “to eliminate the al-Qaeda network, using all elements of our national power to do so—diplomatic, military, economic, intelligence, information, and law enforcement.” The teleconference participants agree that “these concepts would have to be focused more sharply against both al-Qaeda and the Taliban in Afghanistan.” [Myers and McConnell, 2009, pp. 161]
Aide Will Note How Quickly the Committee Made Sense of the Attacks – Larry Di Rita, Secretary of Defense Donald Rumsfeld’s special assistant, who is with Wolfowitz at the alternate military command center outside Washington (see (11:00 a.m.) September 11, 2001), will be struck by how quickly the Deputies Committee members have determined who is behind today’s attacks and what the US needs to do in response. “When I look at the notes of the video teleconference, it is remarkable to me how much they started to piece together in so short a period of time what it was and what the likely responses needed to be,” he will say. The attitude of committee members, he will note, is “not so much, ‘We’ve got to go to war in Afghanistan,’” but instead, “This is very likely al-Qaeda.” He will find it “quite impressive, the degree to which these decision makers/policy makers had a sense of it.” He will also be struck by the resolve of the teleconference participants. “Everybody was operating with a clear sense that we had to respond in a very dramatic way, that this was not something that could be handled any other way,” he will comment. [Historical Office, Office of the Secretary of Defense, 6/27/2002 ]
