Sen. Tim Scott of South Carolina on Tuesday said expanded vote-by-mail systems across the country will “work out just fine.”

“I have a lot of confidence in our electoral process. I’m very confident that we will have fair elections throughout this country,” Mr. Scott said on NBC’s “Today” program. “This process of mail-in ballots will prove to work out just fine.”

President Trump has said the only way he’ll lose in November is if the election is “rigged.”
