Sen. Rand Paul (R-Ky.), who said this week that he will block the nomination of Janet Yellen to become the next chairwoman of the Federal Reserve, says in a new interview that he thinks Yellen will  be confirmed to the post anyway.

Paul has said he will block Yellen unless the Senate takes up his legislation to audit the Federal Reserve. But he said he will likely fail to stop her.

“In all likelihood, yes," Paul said in an interview on Bloomberg's "Political Capital with Al Hunt," which will air Friday night. "But I want to draw attention to the fact that Audit the Fed has been held hostage by [Senate Majority Leader Harry] Reid for three years.  And once upon a time, he was for Audit the Fed.  We had floor speeches all through the '90s, he would come down here with Sen. [Byron] Dorgan, and they were for auditing the Fed.  My question is, let us have at least a vote on this.”

Paul added: “In the old days, you could place a hold on and keep it forever.  Even if I stand on the floor and filibuster in a personal fashion, I can only hold it there for two days.”
