Dozens of Secret Service staffers who attended President Donald Trump‘s rally in Tulsa on Sunday have been told to self-quarantine after two of the agents who attended the rally tested positive for coronavirus.

Two of the six campaign staffers who tested positive are the Secret Service agents.

Following the incident, Secret Service agents involved with Trump’s trips are now required to be tested 24 to 48 hours before his travels. This new testing protocol will be mandated until July 4.

A Secret Service official claimed that the quarantining will not affect the agency’s tasks. 

“The U.S. Secret Service remains prepared and staffed to fulfill all of the various duties as required. Any implication that the agency is in some way unprepared or incapable of executing our mission would be inaccurate,” Secret Service spokesperson Catherine Milhoan told CNN.

Trump’s Tulsa rally did not require its attendees to wear face masks or follow social-distancing protocols.

Moreover, the attendees had to sign a waiver form that prevents the Trump campaign from any liabilities relating to coronavirus or any other health issues.

Tulsa’s fire department revealed that around 6,200 people attended the rally, while the Trump campaign suggests there would be thousands more.
