Pence was on standby to 'take over' during Trump's unannounced Walter Reed visit, new book reports

Vice President Mike Pence was put on standby to temporarily assume the powers of the presidency during President Donald Trump's unannounced visit to Walter Reed hospital in November 2019, according to a copy of New York Times reporter Michael Schmidt's forthcoming book obtained by CNN.

Trump had undergone a "quick exam and labs" as part of his annual physical out of anticipation of a "very busy 2020," the White House had said of the trip at the time.
Schmidt writes, however, that he learned "in the hours leading up to Trump's trip to the hospital, word went out in the West Wing for the vice president to be on standby to take over the powers of the presidency temporarily if Trump had to undergo a procedure that would have required him to be anesthetized." Schmidt does not specify the sourcing for this reporting beyond "I learned."
The White House declined to comment on the record to CNN about the report.
