“We think it’s going to have a very good ending for us. That I can assure you,” he said.

MARCH 6: President Trump’s visit to the Centers for Disease Control and Prevention turns into a scattershot defense of his administration’s handling of the outbreak, veering into political score-settling and exaggerations.
