"Over the past two-and-a-half years, the Obama administration has significantly escalated our military, diplomatic intelligence and economic efforts to disrupt, dismantle and defeat al Qaeda in Afghanistan and Pakistan and around the world," Reid said.

Obama announced on Sunday night that the U.S. had killed bin Laden in an operation in Pakistan.

Lawmakers credited both Obama and Bush in their statements hailing the terror leader's death, and have thus far avoided overt partisan politicking on the matter.

Reid said the fight against terrorism must continue.

"We know that the fight against terrorists who want to harm America is not over," said Red. "We know that."
