U.S. President Donald Trump on Friday said he was a "realist" who would follow the U.S. Constitution after all legitimate votes were counted, but was waiting to see how U.S. states proceeded in certifying their final election results, a top confidant said. Fox News correspondent Geraldo Rivera, in a post on Twitter and in an interview with the network, said Trump had called him earlier on Friday. Trump told him he would "do the right thing" when all the legitimate votes are counted, Rivera tweeted.
