Senate Majority Leader Harry ReidHarry Mason ReidFeinstein departure from top post sets stage for Judiciary fight Whitehouse says Democratic caucus will decide future of Judiciary Committee Bottom line MORE (D-Nev.) hailed the death of Osama bin Laden as the most significant victory for the U.S. in its nearly decade-long fight against al Qaeda.

Reid echoed President Obama, who announced bin Laden's death late Sunday evening, in announcing bin Laden's slaying by U.S. forces as a major triumph in the pursuit of al Qaeda since the Sept. 11, 2001, attacks.

"This is the most significant victory in our fight against al Qaeda and terrorism, but that fight is not over. We will continue to support our troops and the American civilians who are fighting every day to protect our homeland," Reid said.

The top Senate Democrat added: “Nine-and-a-half years ago, Osama bin Laden masterminded the horrific attacks against the United States that killed nearly 3,000 people. As we remember those who were killed on that dark day in September and their families, we also reaffirm our resolve to defeat the terrorist forces that killed them and thousands of others across the globe. Because of courageous Americans in our military and intelligence community, their leader is now gone.”
