Ali Mohamed helps Ayman al-Zawahiri enter the US for a fundraising tour and acts as his head of security during his stay. At the time, al-Zawahiri is known to have been the head of the militant group Islamic Jihad since the late 1980’s. He is also al-Qaeda’s de facto number two leader, though this is not widely known. This is apparently his second visit to the US; having previously paid a recruiting visit to the Al-Kifah Refugee Center in Brooklyn in 1989 (see 1986-1993). The exact timing of this second visit is disputed, but New Yorker magazine will report that “people at the FBI” assert “al-Zawahiri arrived in America shortly after the first bombing of the World Trade Center” in February 1993. Al-Zawahiri stays at Mohamed’s residence in Santa Clara, California, posing as a representative of a charity organization. It is said that not much money is raised. [New Yorker, 9/9/2002] Al-Zawahiri will make another apparently more successful fundraising trip to the US in either late 1994 or sometime in 1995 (see Late 1994 or 1995).
