The Constitution is very clear on this matter. The Supreme Court does not have the Constitutional authority to remove a sitting President (and may not even have oversight to determine eligibility). Once a President assumes power, only an impeachment and conviction can remove him.
As we have seen, the Courts are very subject to the political whims of a single individual, and the public has no oversight of the Courts. The Founders likely did not want to leave the authority to remove a President up to such whims.
Thus, only the legislature can remove him. Assuming office fraudulently would certainly fall within the purview of a “high crime and misdemeanor”.

There is simply too much corruption and cowardliness in the legislature to initiate removal.
We are screwed. Can't say our founding fathers didn't warn us. Freedom is hard won but so easily lost.
That's a matter of opinion, but it doesn't seem very clear to me.

If he's not Constitutionally eligible, is he really the "sitting President"?
