Yesterday, John Brennan was confirmed as CIA Director despite the efforts of many of us to stop his nomination. Senator Rand Paul was among the more vocal, leading a 13 hour filibuster. I commend Senator Paul for holding the President accountable and for his persistence in trying to get a simple question answered from the administration: “Do you believe that you have the legal authority to kill a U.S. citizen on U.S. soil without due process?”

We got an answer to that question, but there were many other troubling aspects of Mr. Brennan's nomination. While Senator Paul was filibustering, I was in the Senate chamber making sure Majority Leader Reid didn't try to end the filibuster, which he could have at any point, and sharing the other concerns I had with Mr. Brennan's nomination with my colleagues. Along with his role in the Obama administration’s controversial drone program, there remain many unanswered questions about Benghazi, which happened on his watch, and his support for closing our facility at Guantanamo Bay (GITMO) and instead trying terrorists in civilian courts. This is why I ultimately voted against confirming him yesterday.
