President Donald Trump is protected at the White House by snipers, sensors, a new 13-foot-tall fence, and a dozens-strong force of Secret Service agents, but none of that managed to keep out the deadly and wily virus that infected him and has killed more than 211,000 Americans. Nonetheless, the President went back to the Oval Office on Wednesday, less than 48 hours after being released from Walter Reed National Military Medical Hospital and still undergoing aggressive treatment.
