President Trump this week joined the growing chorus of calls to punish federal judges who rule against his administration. But impeachment and removal are unlikely under the current makeup of Congress.

“For more than two centuries, it has been established that impeachment is not an appropriate response to disagreement concerning a judicial decision. The normal appellate review process exists for that purpose,” Roberts said in a statement that did not mention by name either Trump or Boasberg.

The attacks on the judiciary by President Trump and his allies have increased in recent days, with calls to impeach a judge who ruled against the president on deportations.
