Finding that he was improvidently seated results in his removal from office, replacement using the line of succession, disgracing Congress for finding an ineligible president-elect, and accepting all of the actions undertaken while Obama was in office to be VALID. De facto officer doctrine takes care of that. Not used often, but it has been used.
