Robert Mueller’s witch hunt against Trump is picking up steam.

He’s impaneled a grand jury and executed search warrants to intimidate Trump associates.

Now he’s making a move that is the most direct threat to Trump yet.

Mueller is aiming his investigation at the White House.

He’s looking to question current administration officials about Trump’s decision to fire former FBI Director James Comey as well as other meetings.

Newsweek reports:

“Current and former members of the administration may face questioning from Special Counsel Robert Mueller in the ongoing probe into Russia’s alleged intervention in the U.S. election.

According to three people familiar with the topic, Mueller is seeking information from the White House about specific meetings and notes on such meetings, and wants to ask people about Trump’s decision to fire former FBI director James Comey, the sources told The New York Times.

Among those likely to be questioned by Mueller is former Chief of Staff Reince Priebus, who may be able to answer questions from the special counsel about both the election campaign and meetings held in the White House since Trump’s inauguration.”

White House advisors are suspicious of Priebus – who never made his way into Trump’s inner circle – and are worried he could flip.

Newsweek also reports:

And despite advisers close to the president, including Ty Cobb, the president’s special counsel, telling The Times the White House would “continue to fully cooperate” with Mueller’s requests, the potential questioning of Priebus is said to be a matter for concern among some in Trump’s circle.

The president was reportedly never convinced that Priebus would be loyal to him, confidantes of Trump told The Times, prompting fears about potential conversations the former chief of staff could have with Mueller.

Of particular interest to Mueller will be any information Priebus may have about the president’s relationship and dealings with ousted FBI director James Comey.

According to testimony from Comey, Priebus was aware of the conversation Trump and Comey had in which the president allegedly told Comey to go easy on General Mike Flynn, telling the then-FBI director “I hope you can let this go,” over the FBI investigation into Flynn, according to a memo from Comey.”

But why is Mueller investigating the decision to fire Comey?

Removing the FBI Director for any reason is a lawful power of the President.

And contrary to popular media narratives, the FBI reports to the Department of Justice who reports to Trump.

It is well within Trump’s power to order an investigation or ask for one to be shut down.

The President cannot obstruct justice by lawfully executing his duties.

So Mueller cannot be investigating Trump for a crime.

What he is hoping for is that Priebus will come home to the establishment and help Mueller build a political case for Trump’s impeachment.

Impeachment does not have to involve a crime.

It’s a political move made by Congress.

Mueller is working with Priebus to build a case that Trump allowed politics or personal relationships to cause him to wonder if Comey could let Flynn go.

That would be the basis for impeaching Trump.
