That is true, but he keeps naming obvious scum.
Look at this bit on his latest NSA, named in September (from wikipedia):
“In October 2011, O’Brien was named to Mitt Romney’s advisory team as Co-Chair of the International Organizations Work Group.[15]
Later, in May 2015, he became an adviser on foreign policy and national security affairs for Wisconsin Governor Scott Walker’s presidential campaign.[16][17] After Walker left the race, O’Brien advised Ted Cruz’s campaign.[17] During the time he advised Ted Cruz’s presidential campaign, he claimed: “It’s clear that Vladimir Putin just doesn’t like [Hillary Clinton], and is going to do what he can to help Donald Trump.”[18]”
O'Brien is way too busy cleaning house at the rat infested NSC to stab Trump in the back.
