Sen. Rand Paul (R-KY) said on The Factor that Hillary Clinton is not fit to be president and "should be in prison."

Paul told Eric Bolling that the former First Lady should face indictment both for the secrets she exposed by using a private email server and for the "pay-to-play" allegations connected to the Clinton Foundation.

He emphasized that the daily schedule for Ambassador Chris Stevens, who was killed in Benghazi, was found in one of Clinton's emails

"You can understand why he wouldn't have wanted the jihadists to know where he was, when he was and why that was inexcusable that Hillary Clinton would put that out there and not put it in a secure place," said Paul. 

He said that in his view, FBI Director James Comey seemed to want to indict Clinton and probably "feels guilty" that he didn't. 

Turning to the new Clinton Foundation allegations, Paul recalled that Bill Clinton got $750,000 from a bank that was negotiating the purchase of a North American uranium company. The deal needed to be approved by Clinton's State Department.

"I think it's indictable. I think she should be in prison for it. But short of that, I think every voter needs to know that the Clintons are in it for themselves, they're in it to make money and they will make hundreds of millions of dollars if she gets into the White House because they will sell themselves to the highest bidder," he said.
