CIA Director John Brennan pushed back against Donald Trump's claim that he could read disapproval of President Barack Obama's policies in the body language of the intelligence officers who gave him a confidential national security briefing.

"I'm pretty good with body language," Trump said during NBC's "Commander-in-Chief Forum" last week. "I could tell they were not happy."


But Brennan said he was "fully confident" they'd done no such thing in an interview with John Dickerson on CBS' "Face the Nation" on Sunday.

"I know the briefers that have been briefing the candidates," Brennan said. "They are the quintessential professional intelligence officers. They do their work very well."

"We don't comment on policy," Brennan added. "We don't give policy recommendations, so I am fully confident that they comported themselves with the utmost professionalism and demonstrated their real breadth and depth of intelligence capabilities."

Trump's comments also drew criticism last week from former top intelligence officials, who are freer to speak their minds than Brennan.

“I’ve never seen anything like that,” Michael Hayden, who served as CIA director under George W. Bush, told POLITICO last week. "That's just awful," he added.
