That’s false, and it only took Cuomo seconds to prove it.

Trump tweeted his criticism of Cuomo Thursday morning, repeating his claim that the network is “fake news”:

Chris Cuomo, in his interview with Sen. Blumenthal, never asked him about his long-term lie about his brave "service" in Vietnam. FAKE NEWS! — Donald J. Trump (@realDonaldTrump) February 9, 2017

Minutes later, Cuomo and his colleagues David Gregory and Alisyn Camerota read Trump’s tweet out loud on CNN, and debunked it immediately with video.

"The President ... is once again off on the facts": @ChrisCuomo's response to @realDonaldTrump's tweet about him https://t.co/ckWo75HT8L — CNN (@CNN) February 9, 2017

”[That was] literally the first point I made in the interview,” Cuomo said. “The president, with all due respect, is once again off on the facts. That’s not something that any of us have any desire to say on a regular basis, but it keeps being true.”

CORRECTION: This post has been updated to reflect that Alisyn Camerota, not Poppy Harlow, appeared on CNN with Cuomo Thursday morning.
