"I don't think that's true," Trump replied.



“That is true,” Walker insisted.



Deborah Birx, a doctor who serves as the White House's coronavirus response coordinator, jumped in to share correct statistics.

"Are you going to apologize, Yahoo?" Trump asked. "That's why you’re Yahoo and nobody knows who the hell you are."

"Nobody knows who you are, including me,” Trump later said. "You ought to get your facts right."

Walker later took to Twitter to apologize to the president, saying he had misread a testing chart.

"In the Oval Office, I asked about test rates and infection rates compared to South Korea. President Trump and Dr. Birx said I was wrong that they've done more tests per capita. Trump said I should apologize. They did not address multiple questions about our higher infection rate," said Walker in a tweet to his more than 43,000 followers.

"We have passed South Korea in the number of tests conducted per capita. I misread the mobile version of this chart and am sorry about that, @realDonaldTrump. Our infection rate is far higher though as I noted," the reporter wrote.
