"Ambassador @McFaul is a patriot who has spent his career standing up for America," Clinton tweeted. "To see the White House even hesitate to defend a diplomat is deeply troubling."
McFaul was a professor at Stanford and also, IIRC, member of the Hoover Inst. prior to being recruited as a token ‘conservative’ by Obama. Not sure about ‘spending his career standing up for America” as Clinton tweeted.
