President Donald Trump is revoking the security clearance of former CIA director John Brennan, who served in the Obama administration.

White House spokeswoman Sarah Huckabee Sanders announced the decision at a White House briefing Wednesday, following through on the president's recent threat.

Sanders is citing Brennan's "erratic conduct and behavior" and accusing him of "lying" and "wild outbursts."

She also claims he's "leveraged his status" to make unfounded allegations.

Brennan has been deeply critical of Trump's conduct, calling his performance at a joint press conference with Russian President Vladimir Putin in Finland "nothing short of treasonous."

Sanders says other former intelligence officials' security clearances are also "currently under review."

The White House announced in the end of July that it was "exploring" the possibility of revoking the security clearances of several former intelligence officials who have criticized Trump. According to Sanders, the White House is now evaluating the clearances of the following individuals on a "case by case basis":  

James Clapper, former Director of National Intelligence 

James Comey, former FBI director

Michael Hayden, former CIA director

Sally Yates, former Acting Attorney General 

Susan Rice, former National Security Adviser 

Andrew McCabe, former deputy FBI director

Peter Strzok, former FBI agent 

Lisa Page, former FBI lawyer 

Bruce Ohr, former Associate Deputy Attorney General 

Not everyone on this list appears to still have a security clearance. In July, a spokesperson for McCabe tweeted that the former FBI director's security clearance was he was deactivated when he was fired. The same apparently is true of Comey, according to his friend Ben Wittes, because he was also fired. Meanwhile, Hayden said last month that revoking his clearance wouldn't have any effect on what he says.
