Without a mask, Trump tours mask distribution center

Trump, a Republican who is running for re-election in November, has resisted wearing a mask in public despite his administration's guidance to Americans to wear them and new White House rules requiring that staff wear them at work.

The president toured the Owens & Minor Inc distribution center, which the White House said has sent millions of N95 masks, surgical gowns and gloves to hospitals and surgery centers across the United States.

Company officials wore masks.

Trump visited a mask production facility in Arizona last week, when he also did not wear a face covering, though he said he tried some on before touring the facility.

Pennsylvania is a political swing state wooed by both Republicans and Democrats in presidential elections. Though the Thursday event was arranged by the White House, it had campaign overtones, with music similar to what is played at Trump's rallies and a pejorative reference by the president to his expected Democratic challenger, former Vice President Joe Biden.
