President Trump repeatedly refused to say on Wednesday whether he would commit to a peaceful transition of power if he loses the election to Joe Biden, saying at a press briefing: "We're going to have to see what happens." The big picture: Trump has baselessly claimed on a number of occasions that the only way he will lose the election is if it's "rigged," claiming -- without evidence -- that mail-in ballots will result in widespread fraud. Earlier on Wednesday, the president said he wants to quickly confirm a replacement for Justice Ruth Bader Ginsburg because he believes the Supreme Court may have to decide the result of the election.
