I can’t recall any member of the military, besides Col. North, testifying in uniform.
Col. North was an active duty officer working in a military chain of command and testified to his actions as directed by his superiors.
This dirtbag was not working in that capacity, was working as a political appointee for a political appointee and NOT representing the military service.
If he had authorization to appear in dress uniform from his immediate commanders and to testify on a political issue then the commanders should be questioned. As far as is known, he had no authorization to take part in or testify regarding a political issue. Brennan is not in his chain of command.
