Sen. Rand Paul charged Tuesday that any senator who opposes his amendment to sunset America's current war authority and approve new ones before continuing U.S. military efforts overseas opposes the language already written in the Constitution.

Paul has delayed work on the National Defense Authorization Act in an effort to get a vote on his amendment and has said he would try to thwart the NDAA at all turns over his language. His amendment would sunset two AUMFs that he and others say are being used improperly to fight wars against terrorism all around the globe.

"Does anybody in America think that the war in Yemen is in our vital interest?" he asked on the floor Tuesday afternoon. "Most people don't know where Yemen is, much [less] think it's in our vital interest."

"If you think we should be at war with Afghanistan, vote for it," he said. "If you think we should be at war in Yemen, come down to the floor and vote for it."

"What does everybody do? Pass the buck. Let the president do it. Let the president take the blame if things don't go so well. We should vote," Paul said.

He said most senators would vote down his amendment, which Paul said is the same as saying, "We don't want any responsibility."

"My vote is on whether or not we should vote on whether we should be at war. So for those who oppose my vote, they oppose the Constitution," he said. "They oppose obeying the Constitution, which says we are supposed to vote."

"They're going to say, 'No, I refuse to vote on any of these wars,'" Paul concluded.

Paul was given a block of time to talk about his amendment, and the Senate is expected to take up the NDAA on Wednesday.
