The president should be impeached and removed from office. If at all possible this should be done tomorrow. Normal procedures, for hearings in the House and a lengthy trial in the Senate should be set aside. Only a single article is needed. The charge should be sedition. It can be drafted tonight, debated in the morning and voted out of the House by lunchtime. The Senate can suspend its rules and move to summary judgement. Allow for four hours of debate and then call the vote.
I don't know if he has become mentally unhinged as some of his close supporters are privately saying, and I don't care. He has violated his oath of office in a manner so brazen that if he is not removed, I am not sure the country can survive the precedent.
Update: The likelihood of removing Trump before the end of his term appears to be going downhill very rapidly. The Democratic majority leader has announced that the House will not sit again until after the inauguration. And with the resignation of Transportation Secretary Elaine Chao it seems unlikely the cabinet will act to invoke the 25th amendment.
Update II: Maybe Stenny Hoyer spoke too soon. Speaker Pelosi has now threatened swift impeachment if Trump is not removed via the 25th amendment.
