After this impeachment they’ll start on trying to impeach Trump’s judicial appointments.
Actually I believe they will try to impeach Pence first. In November numerous news stories tried to tie Pence to all of what is going on now with Ukraine. Then they will focus on impeaching the judicial appointments. The reasoning here is that even if a judge is impeached it leaves a vacancy which can be filled in with another conservative as long as a Repube is in office.
