How ridiculous. Did Hillary "challenge" Trump to prove he won the election in 2016? I don't remember anything like that happening.
I do remember her conceding (reasonably) gracefully, however.
Trump said Biden had to prove he won. Actually whoever brings a claim needs to prove it, so Trump is obviously being a douche.
So - dumb question - but what if somehow the Electoral College votes for Trump on December 14? He stays in office, despite losing the election? Someone please help me out here.
It is a possibility since some states allow Faithless Electors - but not all of them.
