Vice President Mike Pence said in an interview with Fox News on Tuesday that he does not “recall” being told to be on standby to assume the powers of the presidency if President Trump was put under anesthesia during his sudden visit to Walter Reed Medical Center last November.

Why it matters: The White House has never fully explained Trump’s visit to Walter Reed amid the impeachment fight, describing it only as a “routine, planned interim checkup.” New York Times reporter Michael Schmidt reports in his new book that “word went out in the West Wing for the vice president to be on standby,” but that Pence never assumed office.

Driving the news: On Tuesday, Trump tweeted: “It never ends! Now they are trying to say that your favorite President, me, went to Walter Reed Medical Center, having suffered a series of mini-strokes. Never happened to THIS candidate – FAKE NEWS. Perhaps they are referring to another candidate from another Party!”
