Rand Paul, R-Ky., fired back at John McCain, R-Ariz., and Lindsey Graham, R-S.C., on Thursday after the two senators had attacked Paul’s views on the United States’ drone policies, according to a report.

Paul criticized McCain and Graham, who had lambasted his filibuster on Wednesday and early Thursday, which in essence was a protest against the United States' drone policy, the Hill reported.

“They think the whole world is a battlefield, including America, and that the laws of war should apply,” Rand said in an interview on Fox News.

According to the Hill, McCain and Graham had said that Paul’s views on the domestic use of drones were “ridiculous.”

Paul gave his filibuster in the Senate to protest a letter from Attorney General Eric Holder that had left open the possibility that the U.S. could stage a drone strike on domestic soil under certain circumstances.

“The laws of war don't involve due process, so when they ask you for an attorney you tell them to shut up. That's not my understanding of the way America works,” Paul said on Fox News. “I don't think the laws of war apply to America, I think the Bill of Rights do and I think it's a disservice to our soldiers that our senators [are] up there arguing that the Bill of Rights aren't important."

The filibuster stalled John Brennan's nomination to head the CIA as a means to protest Holder's letter and the Obama administration's lack of clarity on its domestic drone policy.

“This was a very serious question," Paul said. "It was a question that took a month and a half to get an answer to and so I would argue -- and I think a lot of the public would agree with me, both on the right and the left -- that what we ask was a very serious question and it's a question that we finally got an answer to."
