Theodore Deutch actually said...

The Constitution provides constraints on presidents and vests this body with the monumental power of impeachment.

I have long been skeptical of the arguments vesting the President with absolute immunity from any criminal proceedings while he is in office...

The failure to impeach in that circumstance leaves the American people with a criminal in the White House.

Was Special Counsel Mueller able to pursue any of these remedies for potential misconduct by President Trump?
