Doctor: Trump improving, but not 'out of the woods' yet

President Donald Trump went through a “very concerning” period Friday and faces a “critical” next two days in his fight against COVID-19 at a military hospital, his chief of staff said Saturday — in contrast to a rosier assessment moments earlier by Trump doctors, who took pains not to reveal the president had received supplemental oxygen at the White House before his hospital admission. Hours earlier, chief of staff Mark Meadows told reporters outside the hospital, “We're still not on a clear path yet to a full recovery.” In an update Saturday night, Trump's chief doctor expressed cautious optimism but added that the president was "not yet out of the woods.”
