Interesting, briefing congress on what is likely entirely truthful information but unfavorable to the president, replaced immediately "for allowing it to take place" with who person who is alleged to be an even more staunch right wing sycophant.
Of course Trump is going to appoint a Republican that he thinks will support his policies, just like Obama and every other president does. Your character assignation of Grenell is not supported by evidence. As a long time ambassador, gay guy that worked for Romney and Bush, I don't think 'extreme' or 'sycophant' is a fair characterization. Is every Democrat that worked for Obama an extreme left wing sycophant?
If they were on record, very publicly and very frequently spousing extreme liberal views then yes, they would be fair to be considered so.
Can you name even one DNI appointee by any other recent president who had such a reputation (conservative or liberal)? Hint: You can't.
No other president from either side has ever named such a blatant partisan candidate to the position of DNI because all other presidents have understood just how sensitive and critical that position is.
Let's be clear here: This isn't about a post like say, Whitehouse Spokesman. There are plenty of positions in the executive branch where it is not only fine but actually makes perfect sense to appoint a very partisan person. But the DNI is not one of them. The Director of National Intelligence is just too sensitive and dangerous of a position to mess with.
If Obama had named someone like, say, AOC to the DNI post, that might be an equivalent. Someone who is on the far left and, similarly, has zero experience working in the IC community. But he didn't. He, like all the other presidents before him, named someone who was a long-term career IC/Military professional (Clapper). Someone who got _unanimous_ approval by the Senate. The _only_ resistance to his nomination actually only came from a few folks on the left who thought he was too defense-oriented of mind for the head of a civilian post. But even that resistance was pretty tiny. Again - he got every vote from both parties in the Senate.
Unlike Grenell, who it was clear would not even get supported by a Senate controlled by his own party.
