Washington (CNN) President Donald Trump said again on Friday that Americans need identification to buy groceries, which remains not true.

"You know, if you want to go out and buy groceries, you need identification. If you want to do almost anything you need identification. The only thing you don't need identification for is to vote, the most important single thing you're doing -- to vote," Trump said at a campaign rally in Lake Charles, Louisiana.

Trump added: "You know why? Because they cheat like hell, that's why." Voter fraud is exceedingly rare, and there is no evidence of mass cheating by Democrats.
