Trump was introduced to red and yellow cards in 2018

President Donald Trump said earlier Monday that he didn't know what a red card was before last Wednesday's U.S.-Bosnia match.

But FIFA President Gianni Infantino actually gave him a lesson on soccer's disciplinary system during a 2018 Oval Office meeting after the United States secured the right to co-host the 2026 World Cup.

During the visit, which followed the successful United Bid, Infantino explained the sport's use of yellow and red cards before pulling one of each out from a case.

"In soccer we have referees and they have cards: yellow cards and red cards," Infantino told Trump. "Yellow card is a warning, and when you want to kick out someone, a red card. Like this!"

Trump appeared amused by the demonstration.

"I like that," he said picking up the red card and holding it up. "Thank you."

Infantino then joked that the cards might come in handy beyond the soccer field.

"That could be used for, I don't know, the next media session," he said.
