I still don't see any meat on the bone that Trump's appropriate (IMO) criticism of Sessions is somehow wrong. It is basically a much more critical version of 'The Apprentice'.
Since Sessions was appointed US AG, he let himself be bullied into un-necessarily recusing himself from a massive case against the President. Without him 'in the way' Mueller then loaded his Counsel with the 'murderers row' of Trump donors and Clinton lawyers with which to go after Trump.
Illegal leaks were pouring out of the WH, the former Director of the FBI admitted under oath he illegally leaked information while testifying that former US AG Lynch illegally obstructed Justice. The FBI also just released more than 400 more new pieces of evidence against Hillary Clinton of illegal non-compliance with the FOIA and the Federal Records Act. It has also been revealed that Former Obama Cabinet member Susan Rice illegally shared records and illegally unmasked Americans for political purposes.
It's been like a cattle town the 1st night after the cowboys have brought in the herd, and the town has no sheriff - wild, crime, no sheriff, no justice.
Sessions has been exposed as weak, meek, easily intimidated, and without initiative to do his job. It took an ass-chewing from Trump to get him to step up and do his job.
- People criticized Trump for doing the ass-chewing. Sorry, they are wrong in one aspect. An ass-chewing is exactly what was needed. In my own professional mentorship I take the individual aside, though, and deliver the 'wall-to-wall counseling' in private. Trump doing so in person tells me he wanted it to be public, to let people know he was not happy with Sessions and why...so when / if he fires him there will be no misunderstanding why he did / does so.
What happens next, like with the people I have counseled, is up to HIM / THEM. Sessions can take the initiative and step up his game...or hear the words people tuned in to the Apprentice to hear: 'You're Fired'.
