Josh Bolton should call up all of the Democrat Committee chairmen and chairwomen in both houses and inform that no more Executive Branch officials will be testifying before their committees until their personal security is assured and that further testimony will resume only after Code Pink has been completely excluded from the sessions.
I “second” your recommendation, but would add that, until Congress can prove that it is competent enough to provide security for Executive Branch officials, all future “testimony” requested by Congressional Committees will be given in meeting rooms provided by, and secured by, the Executive Branch.
