US President, Donald Trump’s physician on Tuesday, said that Trump did not have a stroke and he remained healthy in response to a new book which suggests Vice President, Mike Pence was to be put on standby for presidential powers during Trump’s last year medical visit.

Michael S. Schmidt, New York Times reporter in the book titled, ‘Donald Trump v. The United States’ writes that last November, the vice president will be on standby if Donald Trump undergoes a procedure in which he will be anaesthetized. In an interview on Tuesday, Mike Pence said that he doesn’t recall being told to standby but was informed that the president has a doctor’s appointment.

Last month, author Don Winslow tweeted that he had received three communications from administration whistleblowers that Donald Trump had “a series of mini-strokes.”

Dr Sean Conley in a statement said: “I can confirm that President Trump has not experienced nor been evaluated for a cerebrovascular accident (stroke), transient ischemic attack (mini-stroke), or any acute cardiovascular emergencies, as have been incorrectly reported in the media”. Conley said that the president remained healthy and he has no concerns about the president’s ability to maintain a rigorous schedule. “I expect him to remain fit to execute the duties of the Presidency,” he added.

Trump on Twitter has also denied that he was suffering from a series of mini-strokes. But, his unexpected and unscheduled visit to Walter Reed National Military Medical Center triggered questions on social media since it occurred months before his annual physical test that had been carried out in the past.
