Trump's doctor says in an update that he's 'not yet out of the woods' as the White House releases photos from his hospital suite

• President Donald Trump's main doctor said in an update on Saturday he's "cautiously optimistic," but that the president is "not yet out of the woods."
• Earlier that evening, Trump tweeted out a lengthy video updating Americans on his condition and saying he hoped to "be back soon" but that the coming days would present "the real test."
• Late Saturday night, the White House also released two photos showing Trump as he "works from Walter Reed."

President Donald Trump's main doctor says in a health update that the medical team treating the president is "cautiously optimistic," but also notes that the president is "not yet out of the woods."

The latest assessment came Saturday night from Navy Commander Dr. Sean Conley. He reported that Trump had been up and around at his medical suite during the day and had been conducting business.

Conley added that Trump had completed his second dose of the antiviral drug remdesivir "without complication."

He said Trump "remains fever-free and off supplemental oxygen." Earlier that day, Conley had sought to dodge reporters' questions about whether Trump had received supplemental oxygen — media outlets later reported that he had received it on Friday, before arriving at Walter Reed.

Medical experts say the disease caused by the virus, COVID-19, can become more dangerous as the body responds to the infection over time.

Trump is expected to remain at Walter Reed National Military Medical Center for several more days.

Earlier on Saturday evening, Trump tweeted out a lengthy video updating Americans on his condition and saying he hoped to "be back soon" but that the coming days would present "the real test."

Trump, who looked paler than usual but appeared to speak and breathe well, said in the video he was "starting to feel good," though he acknowledged that when he first arrived at the hospital he "wasn't feeling so well."

"I feel much better now. We're working hard to get me all the way back. I have to be back, because we still have to make America great again," he said.

Late Saturday night, the White House also released two photos showing Trump as he "works from Walter Reed."
