There are only two levers of power over a sitting President:
1. The voting public at election
2. The US Congress upon Impeachment and Conviction
That’s it.
There is nothing else.

Right.
A sitting president cannot be indicted and there are no grounds for impeachment.
The House makes it own determination of what high crimes and misdemeanors are in its impeachment trial. I am sure the Democrats and Never Trump Republicans can be creative. The President and his close associates are still in grave legal jeopardy.
