Possibly ABC knows how corrupt it is for Mueller to hire all dems or Trump haters for his staff and then suggest there will be anything fair at all about his investigation.
Plus the cost is skyrocketing acknowledged by Kellyanne. Mueller needs to be fired which indirectly Trump can probably manage,might need a little help from Sessions.
I think appointment of a SC was inevitable, there is and was a need to dispose of the investigations that Comey revealed to the public on March 20th. Trump appointees would not be trusted by the press, to deal with those. The SC has to run its course. The thing to push for is speedy resolution, and the more people working on the project, the faster it is wrapped up.
Trump has consistently said he wants the investigation, it is the only way he can clear the accusation by innuendo.
If he fires Mueller, the "guilty" and "hiding something" accusations goe up by a factor of 100.
