Hostile former officials could lose security clearance

Washington Examiner:

President Trump is considering revoking the security clearances of several former intelligence and national security officials who have been critical of his administration, the White House said Monday.

"Not only is the president looking to take away [Former CIA Director John] Brennan's security clearance, he's also looking into the clearances of Comey, Clapper, Hayden, Rice and McCabe," press secretary Sarah Sanders told reporters.

The White House accused those individuals of having "politicized and monetized" their access to U.S. intelligence and national security secrets.

"As of right now, we are exploring the mechanism on those specific names," Sanders said.

Sanders rejected the idea that Trump was considering the move as a way to punish his political enemies, and said the issue was how people with a security clearance were abusing that privilege.

Some of these people appeared to have abused the privilege prior to the transfer of power.  Some of them openly accused the President of colluding with the Russians to win the election.  There has been an obvious lack of evidence to support that charge.
