His proof was, according to the New York Times, a single anecdote from a German golfer named Bernhard Langer who claims to have never met Trump — and who isn’t registered to vote in this country anyway — as well as a whole lot of racial profiling.

“The three witnesses recalled Mr. Langer being the protagonist of the story, although a White House official claimed the president had been telling a story relayed to the golfer by one of Mr. Langer’s friends,” the Times wrote Wednesday.

According to the anecdote, the championship golfer Langer was told by an election official that he would not be permitted to vote while standing in the waiting line on Election Day. Trump described Langer as saying that there were voters in front of and behind him “who did not look as if they should be allowed to vote” before rattling off some Latin American countries as possible ethnic origins for these hypothetical voters.
