"If I lose to [Biden], I don't know what I'm going to do. I will never speak to you again," Trump told supporters at a rally in North Carolina.
Trump made similar remarks in 2016 when he rivaled Hillary Clinton for the presidency: "I don't think I'm going to lose, but if I do, I don't think you're ever going to see me again, folks," Trump said. "I think I'll go to Turnberry and play golf or something."
