Nothing legally, but no one will care about a "legal technicality". The Lawyers for The One, and the DNC, will stall for a couple of more weeks, and then we may very well find ourselves with a President Elect who is not Constitutionally qualified for the position. Also with President Elect Biden. (although not until the electoral college casts it's votes, until then, it's not official under the Constitution, and the "O" electors could vote for someone else, say Hillary, or Biden, or John F'n Kerry (who served in Vietnam) or even AlGore, who after all got a plurality of the popular vote. )
Could result in Interesting Times".
But I have to believe that if the evidence was there, Hillary, who wants the Presidency as a wolf wants a sheep, would have found it, and leaked it to the Republicans.
