Between 30 and 50 contributors attended the event, according to individuals briefed on the matter. Many of them have tried reaching out to Trump's team.
"The donors have been texting and calling. Freaking out," a person with direct knowledge of the situation explained.
The Trump campaign has not yet sent out any official guidance to those who attended the event, but they have sent out an email reassuring the attendees that everyone was encouraged to practice social distancing.
"Out of an abundance of caution, we want to call this to your attention. Please be reminded that due to Trump Victory-protocol, no attendees were allowed within 6 ft of President Trump at the event," the email read.
"Please contact your medical provider if you or any of your loved ones is ill or develops a fever, shortness of breath, or other respiratory symptoms."
According to the Republican National Committee, everyone who participated in the gathering had their body temperature measured, stood at least six feet from Trump and got tested for COVID-19.
Although most of the interaction with the president reportedly took place outdoors, donors who have been able to get in touch with officials have been advised to stay home and contact their doctors.
Longtime Republican Party donor Dr. Rich Roberts said that tickets for the fundraiser cost up to $250,000. Trump privately met with 19 people and the meetings lasted around 45 minutes, according to Roberts.
