WASHINGTON (AP) — President Donald Trump’s campaign says six staff members helping set up for his Saturday night rally in Tulsa, Oklahoma, have tested positive for coronavirus.

The campaign’s communications director, Tim Murtaugh, said in a statement that “quarantine procedures” were immediately initiated and no staff member who tested positive would attend the event.

Murtaugh said campaign staff members are tested for COVID-19 as part of the campaign’s safety protocols.

Campaign officials say everyone who is attending the rally will be given temperature checks before they pass through security.

The Oklahoma Supreme Court on Friday denied a request that everyone attending the indoor rally wear a mask, and few in the crowd outside Saturday were wearing them.
