I have been told several times tonight that Recall does not apply to Congressmen or Senators. Only removed by impeachment, the Congress with the Senate hearing the trial.
I am afraid that is the case after examining it.
It might be possible for a member of Congress to be impeached, but it would be silly. Impeachment requires a simple majority in the House and two-thirds in the Senate. Expulsion requires only a two-thirds vote in one house.
The only time impeachment would make sense if the House could get a majority, but not 2/3, for expulsion of one of its members; that’s a fairly narrow case and a lot of rigamarole to remove one rep of 435. There is no case where it would make sense to impeach a senator.
