Biden: Clinton's Biggest 9/11 Failure – Monica Lewinsky

The ranking Democrat on the Senate Foreign Relations Committee said Sunday that President Clinton's affair with White House intern Monica Lewinsky compromised U.S. national security because it left him unable to deal with the threat posed by al-Qaida.

"What really happened here, I think, is President Clinton's greatest mistake was Monica Lewinsky," Sen. Joe Biden, D-Del., told "Fox News Sunday."

"And that forced him to take his eye off the ball. He lost the ability to lead the nation to take some of the action that [White House terrorism czar Richard] Clarke was suggesting."

Biden said the Bush administration's biggest mistake was focusing on a national missile defense instead of al-Qaida.
