Brown,MayorWillie

From 911Encyclopedia:

Mayor Brown was called eight hours before the attack and was warned that "Americans should be cautious in their travel." He cancelled his flights. From an article on September 12, 2001: "For Mayor Willie Brown, the first signs that something was amiss came late Monday when he got a call from what he described as his airport security - - a full eight hours before yesterday's string of terrorist attacks -- advising him that Americans should be cautious about their air travel." http://www.sfgate.com/cgi-bin/article.cgi?file/chronicle/archive/2001/09/12/MN229389.DTL
