If Trump doesn’t personally revoke security clearances, nothing prevents idiot coup meisters like Brennan to continue contact with derp-state operatives to continue the coup operations against Trump. Shut down their comms!!! Sen Ron Johnson is missing the point!
Well, as they say, “In for a penny, in for a pound”.
Anyone that deep in treason with Brennan will not be deterred simply because Brennan no longer has his clearance...
The security clearances do need to be shut down. My guess is he will.
