Elon Musk sought to rally support on social media Wednesday for the impeachment of a federal judge, echoing calls from President Donald Trump and his allies for Congress to take action against judges who rule against the Trump administration.

At least two-thirds of the Senate would have to vote to remove a judge from office, which is unlikely to happen.

“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.
