Trump revokes former CIA director John Brennan's security clearance

The announcement came weeks after Huckabee Sanders told reporters that Trump was looking in to the process required to revoke security clearances from half a dozen former Obama administration officials.

Huckabee Sanders cited Brennan's "erratic conduct and behavior" as the reasoning behind the revocation and accused him of "lying" and "wild outbursts." Brennan has been critical of Trump, calling his performance at a joint press conference last month with Russian President Vladimir Putin in Finland "nothing short of treasonous."

Huckabee Sanders did not say Wednesday that Brennan leveraged his security clearance for financial gain -- an allegation she levied at some former intelligence officials last month.

During a July 23 news briefing, Huckabee Sanders said Trump was exploring options to remove security clearances from former officials who have “politicized and, in some cases, monetized their public service.”

Huckabee Sanders said Wednesday that officials continued to look at revoking the clearances of other former officials, including former FBI Director James Comey and former FBI Deputy Director Andrew McCabe.
