• On September 26, President Donald Trump hosted an event at the White House Rose Garden to honor his nomination of Judge Amy Coney Barrett to the Supreme Court.
• In the days since, the president and a number of people close to him have tested positive for COVID-19, the disease caused by the novel coronavirus.
• Trump left Walter Reed Medical Center in Bethesda, Maryland, on Monday evening, where he had been hospitalized since Friday.
• Here's a timeline of the White House coronavirus outbreak, which involves a number of people who include two GOP senators, the first lady, several close advisers, and the White House press secretary.

President Donald Trump early Friday announced he and First Lady Melania Trump tested positive for COVID-19, and hours later he was admitted to the Walter Reed Medical Center in Bethesda, Maryland, where he was treated with at least three different therapeutic drugs.

Trump's diagnosis came shortly after that of his adviser and former communications director Hope Hicks and not long before two GOP senators and others close to him announced they, too, had tested positive for the novel coronavirus.

Here's how the apparent COVID-19 outbreak at the White House began, from a possible superspreader event on September 26 to Trump's release from the hospital on Monday evening.
