>>> Impeachment is the only constitutional way to get him out now.
You cannot Impeach an illegitimate president, because the legislature is responsible for putting him there!

I've read the USC a few times in my life. The only provision for removing a sitting president is impeachment in the House, conviction in the Senate.
either of the two other branch’s has the power to remove the president in this case. Judicial Branch or congress.

There is also Federal Legislation on Succession, sorry.
