This is not "exoneration" for Trump; if anything, it is an indictment that he hired:

a) a national securiy advisor;
b) campaign chair;
c) deputy campaign chair and WH advisor;
e) personal attorney and deputy national party finance chair

who are all admitted or convicted crooks, and none of which were even remotely trustworthy for the posts they were given...

"I'm not a crook (but my staff was)" didn't work out that great for Nixon, did it?
