According to Fox news
President Trump on Tuesday denied that he had “a series of mini-strokes” prompting an unscheduled visit to Walter Reed hospital in November 2019.
“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,” Trump wrote on Twitter. “Never happened to THIS candidate — FAKE NEWS. Perhaps they are referring to another candidate from another Party!”
