The Republicans on the investigating committee are getting tired of the runaround Director Koskinian is giving them. They ask the President to can him for:
(1) failing to comply with a congressional subpoena,
(2) failing to
testify truthfully, and
(3) failing to preserve and produce up to 24,000
emails relevant to the investigation.
It won't happen of course. That's what the president hired him to do and he's doing a fine job of it.
If you own the cop, you won't get arrested. If you own the judge, you won't get convicted. It's how it works.
