NBC security analyst and former CIA director John Brennan is doubling down on a threat to sue President Trump after the outspoken former Obama official was stripped of his security clearance.

Brennan appeared Friday night on MSNBC and told Rachel Maddow he is exploring litigation against the president. This follows Reps. Elijah Cummings (D-Md.) and Adam Schiff (D-Calif.) saying Trump stripping Brennan of his security clearance is illegal.

“As you can imagine, a number of lawyers reached out to say that there is a very strong case here, not so much to reclaim mine but to prevent this from happening in the future," Brennan said. "So, I am thinking about what it is that I might want to do. At this time, I’m trying to make sure that the principle is what is going to be defended and supported and this is something that should not be repeated."

"The other people on the so-called enemy’s list now, I think this is just another example of Mr. Trump trying to frighten and intimidate others," he continued. "But I can tell you, having worked in the national security and intelligence, these are not the type of people who are bullied or intimidated by the likes of someone of Mr. Trump.”



Today NBC's Chuck Todd asked Brennan if he's "serious" about suing the president. Brennan said that he is.



“Well, I have been contacted by a number of lawyers and they have already given me their thoughts about the basis for a complaint, an injunction to try to prevent him from doing this in the future," Brennan responded. "If my clearances, and my reputation, as I’m being pulled through the mud now, it if that’s the price we’re going to pay to prevent Donald Trump from doing this to other people, to me it’s a small price to pay. I am going to do whatever I can personally to try to prevent these abuses in the future. And if it means going to court, I will do that.”
