Mitt Romney, CNN, the top brass at the FBI at the beginning of 2017 — these were just some of the targets of a verbal lashing from Donald Trump at the daily White House coronavirus briefing on Sunday.While Mr Trump, the vice president Mike Pence, and other White House coronavirus task force officials spent nearly an hour at the podium mounting a public relations campaign to paint the administration’s response to the health crisis in positive colours amid outside criticism from Democrats and health experts, the question-and-answer portion of the briefing turned characteristically chaotic as the president clashed with reporters.
