"I've always liked General Flynn but he's now pleaded guilty to a federal offense. I think he should lose his security clearance," Graham, a member of the Senate Armed Services Committee, told reporters Thursday .

"I can't imagine sharing anything with Brennan given his hatred toward President Trump - I don't think he'd have any constructive input," Graham said, adding that he's "very concerned" with former FBI agents Peter Strzok and Lisa Page and current Justice Department official Bruce Ohr "having security clearances."

White House press secretary Sarah Huckabee Sanders announced that Strzok, Page, Ohr, and another handful of former intelligence or security officials are under review and may lose their clearance.

Senators on Capitol Hill during an unusual August work session largely reacted along party lines, with Democrats and some Republican critics decrying Trump’s decision as a political move to silence an outspoken critic.
