Harris: Comms dir. 'doing well' after virus diagnoses

The Biden campaign said on Thursday that two people involved in the campaign had tested positive for COVID-19, including one on the staff of Senator Kamala Harris, Biden's running mate.

Biden had also been on a plane with an aviation company employee who tested positive but was not in close contact, his campaign said in a statement. He tested negative for COVID-19 on Thursday as well as Wednesday, his campaign said.

While Harris was not in close contact with anyone who tested positive, the campaign said it was canceling Harris' travel until after Sunday as a precaution, although Biden's schedule will be unaffected.
