Thanks for the new thread Claws.
For a bit of general clarification on previous posts (and being a bit pedantic), Scrotus has been impeached. He was impeached in the House of Representatives (in whom rests the sole power of impeachment) on two articles: Obstruction of Congress and Abuse of Power. As Claws says in the title the next step is a Senate trial and a verdict (by vote) as to whether or not to remove him from office. The Senate has sole power to try the President and to remove him from office.
Spkr Pelosi doesn't have to submit the Articles to the Senate for trial on any timetable. As it stands, she's waiting to see if a fair and impartial trial can be guaranteed by Moscow Mitch and his cronies. If not, she can hold the Articles indefinitely. She can even hold them until immediately before or just after the 2020 election.
Yes, we'd have Pres Pence if Scrotus was removed, but his tenure would be short as the election is next November. And the party may well want a candidate without the 'Trump Taint'.
There are already lawsuits moving through the system that will impact Roe v Wade. Chances are they'll be heard after Scrotus leaves office.
