On Tuesday, Republican Senator Rand Paul slammed former CIA director John Brennan, labeling him "completely unhinged" and questioned his bias during his time with the intelligence agency.
FOX News host Martha MacCallum asked Paul about the comments made by Brennan that President Donald Trump is treasonous.
She played a clip of Trump’s interview with Tucker Carlson where the Commander-in-Chief said of the former Obama appointee, "I think he's a very bad guy and if you look at it, a lot of things happened under his watch. I think he's a very bad person."
"I agree completely," said Paul. "I think John Brennan's completely unhinged and you see him now calling the president treasonous."
He continued: "What should worry every American is John Brennan was in charge of the CIA, the most powerful intelligence gathering group on the planet."
Senator Paul also expressed his concern over the possibility of the intelligence agency analyzing private citizens’ personal information without seeking a warrant.
"They can absorb every bit of information you can imagine, your phone calls, your metadata, your bank records, your visa records," he said. "They can destroy any person's life. The person at the head of that turns out to be a very much partisan, a Trump-hater and very much just someone who is a, you know, Trump-hater, I guess that's the best way to put it."
Paul emphasized, "I really am worried that he was head of the CIA for so long harboring all of that bias."
