President Bill Clinton rewrites a memo authorizing the CIA to use the Northern Alliance in an operation to assassinate Osama bin Laden. This memo follows another one signed by Clinton the previous year that allowed the agency to use a group of tribal fighters to kill bin Laden (see December 24, 1998). The draft February memo contains similar language to the earlier one, but applies to the Northern Alliance, not just the tribal assets. However, Clinton himself deletes the wording authorizing an operation to simply kill bin Laden. Clinton will later tell the 9/11 Commission that he does not recall why he gives the CIA permission to kill bin Laden through the tribal assets, but not through the Northern Alliance.
