White House incident: U.S. President Donald Trump was abruptly escorted by a U.S. Secret Service agent out of the White House briefing room as he was beginning a coronavirus briefing Monday afternoon, returning minutes later to say there had been a "shooting" outside the White House that was "under control." 

2. Public venues: New data suggests that more than 500 COVID-19 infections in Canada have been linked to public venues including stores, bars, restaurants, daycares and schools since the beginning of July as more businesses continue to reopen and restrictions are eased.
