President Trump on Sunday said in a phone call to a group of supporters that he’s “tested totally negative” for the novel coronavirus, despite White House physician, Navy Cmdr. Dr. Sean Conley, releasing no new statements on the president’s health.

“I’ve been tested totally negative,” Trump said in an audio message his campaign posted on YouTube. “I’m going to be out in Florida tomorrow, working very hard because this is an election we have to win.”

Despite Trump’s claim that he has tested negative for the virus, the White House has not released any information since Conley sent out a memo on Saturday saying the president was no longer at risk of transmitting the coronavirus. Conley did not, however, say explicitly whether Trump had tested negative for it.
