Trump spent Friday working and making calls from his residence, and plans to continue working from the hospital, the official said. Walter Reed has an executive office suite set up for this very purpose, including both a residence and an office space, the official said. The official stressed that Trump is not seriously ill, but because of his age, as well as other risk factors, he and aides decided to take this additional step.

He is expected to travel there on Marine One, and to walk out to the helicopter on his own.
