Has Rep. Cynthia McKinney been vindicated? On a Berkeley radio station in March, the Georgia Democrat called for a congressional investigation of the Bush administration, asking, "What did this administration know, and when did it know it?"

"What do they have do hide?" she asked KPFA's Dennis Bernstein in that March 25 interview. "We know there were numerous warnings of the events to come on September 11." The congresswoman was widely vilified in the national media for such statements. But in light of information that the White House had been repeatedly warned of terrorist threats before 9/11, McKinney's questions have become among the most asked questions in the nation.
