WATCH: Sarah Sanders defends Trump's bizarre claim you need an ID to buy groceries

White House Press Secretary Sarah Huckabee Sanders on Wednesday faltered when asked to explain Donald Trump’s bizarre claim Americans need identification to purchase groceries, insisting the president was talking about purchasing beer and wine.

At a rally in Florida on Tuesday, Trump attempted to bolster his administration’s push for tougher voter I.D. laws, telling the crowd, “if you go out and you want to buy groceries, you need a picture on a card, you need I.D.”

Asked about the president’s remarks, Sanders said Trump “wants to see the integrity of our election systems upheld.”

“He wants to make sure that anybody that's voting is somebody that should be voting,” Sanders said. “And that's something that should be celebrated. Not discriminated.”

“When was the last time the president went to a grocery store?” a reporter asked.

“I'm not sure. I’m not sure what that matters,” Sanders replied as journalists in the room reminded her of Trump’s comment.

“You go to the grocery store, I go to the grocery store, I’ve never had to show an I.D.,” the reporter said. “At the grocery store. I've never had to show an I.D. when I go to buy groceries. Most people don’t.”

“Certainly, if you go to a grocery store and buy beer and wine you'll show your I.D.,” Sanders shot back.

“The president doesn't drink,” the reporter replied.

“He's not saying every time he went in,” Sanders insisted. “He's saying when you go to the grocery store. I'm sure everybody in here who has been to a grocery store that's purchased beer or wine has probably had to show their I.D. If they didn't, then that's probably a problem with the grocery store.”
