judge have the power to do it for themselves.
The APPEARANCE of impropriety is impropriety.
this judge belongs to a racist group which ACTUALLY ADVOCATES THE OVERTHROW OF THE USA! not even pretend loyalty.
This is not judge shopping since the new judge would be randomly assigned as this one.
The even bigger story is here. The judge is a lifetime member of another group (per his Senate Judiciary Committee questionnaire) that started a boycott against Trump and all his businesses back in July of 2015. This presents not just some theoretical conflict, but actual concrete, irrefutable proof of what Trump has been saying about the guy. The group is the
Hispanic National Bar Association.
