From the editorial board of the Philadelphia Inquirer:
Trump has severely disrespected his office and the document he swore to protect and uphold.
Should this process end with a trial and a Senate vote to remove him from office — a prospect that seems highly unlikely — it’s not hard to imagine that he would insist that the process was invalid and refuse to go.
We endorse a vote to impeach the president. While his removal from office is unlikely, his crimes against the country, and the Constitution, warrant that outcome.
