On Sunday, doctors at Walter Reed National Military Medical Center briefed the media on the health of U.S. President Donald Trump. The news conference came after a whirlwind weekend where a growing number of the president’s inner circle, including first lady Melania Trump, tested positive for COVID-19, and where the president's doctors and team issued conflicting messages about his medical status. CBC’s senior Washington editor Lyndsay Duncombe joins us to explain what’s known about the president’s health, how this outbreak could impact the U.S. election and what this means for the nomination of the next U.S. Supreme Court justice.
