Six members of a campaign advance team working in Tulsa ahead of Donald Trump's Saturday rally here have tested positive for COVID-19, his campaign said hours before the president was set to take the stage. "Per safety protocols, campaign staff are tested for COVID-19 before events," Tim Murtaugh, the Trump campaign's communications director, said in a statement. "Six members of the advance team tested positive out of hundreds of tests performed, and quarantine procedures were immediately implemented," Murtaugh said, adding that no COVID-positive staffers "or anyone in immediate contact" with them will be at the rally or near attendees. — Agencies
