Donald Trump appeared to throw another lit match Sunday on his administration’s increasingly combustible relationship with the Democratic-controlled House by signaling that special counsel Robert Mueller should not testify to Congress.

Trump tweeted that “Mueller should not testify.”

….to testify. Are they looking for a redo because they hated seeing the strong NO COLLUSION conclusion? There was no crime, except on the other side (incredibly not covered in the Report), and NO OBSTRUCTION. Bob Mueller should not testify. No redos for the Dems!

“After spending more than $35,000,000 over a two year period, interviewing 500 people, using 18 Trump Hating Angry Democrats & 49 FBI Agents – all culminating in a more than 400-page Report showing NO COLLUSION – why would the Democrats in Congress now need Robert Mueller……. ” Trump tweeted.

“….to testify. Are they looking for a redo because they hated seeing the strong NO COLLUSION conclusion? There was no crime, except on the other side (incredibly not covered in the Report), and NO OBSTRUCTION. Bob Mueller should not testify. No redos for the Dems!” the tweet concluded.

If Attorney General William “Bill” Barr takes the Trump tweet as a directive, it could set up yet one more confrontation between the White House and the House.

Barr has been extremely protective of Trump since Mueller first filed his report on March 22 on the subjects of potential collusion between the Trump campaign and Russia and subsequent obstruction of justice.

Barr, himself, set up a likely standoff last week with the House Judiciary Committee after he failed to appear to testify as previously arranged.

Further, Trump has ordered anyone in his administration–or once was in the administration–from cooperating with any House subpoenas or requests.

In spite of that–and although nothing had been nailed down–Mueller had been likely on track to testify before the House Judiciary Committee May 15. The White House had previously not intended to stand in the way of that testimony.

Mueller technically is an employee of the Justice Department, and as such, is overseen by Barr.
