Sen. Rand Paul (R-KY) spoke to Fox Business host Kennedy in a wide-ranging interview tonight about how he would take on ISIS and his fight against the National Security Agency's mass surveillance program.

Kennedy asked Paul what he accomplished with his fight over the Patriot Act. 

"Actually I think a significant accomplishment was a rebuke to the president," Paul replied. "To say to the president, 'it is illegal to collect our records, it's illegal to collect them and store them in Utah. The court has told you so and now Congress has told you so.'"

He told Kennedy that he agreed with the portion of the USA Freedom Act that eliminated bulk collection of records, but he emphasized that he "didn't want to send those records over to phone companies."

"I still believe that the Fourth Amendment says that records can only be collected with individualized suspicion," Paul added.

"Interestingly, that's a very unpopular position in Washington," he added. "I may well be the most unpopular person in Washington right now."
