In this Thursday, Oct. 1, 2020, photo President Donald Trump steps off of Marine One at Morristown Municipal Airport in Morristown, N.J., after attending a fundraiser at Trump National Golf Club in Bedminster.
Somerset County officials were meanwhile contacting employees who worked the event, most of whom live in the county.
In a joint statement issued Sunday, the officials asked guests and employees to monitor their symptoms and, if they were close to President Trump or his staff, to quarantine for 14 days.
The officials, who started seeking the information on Friday, said on Sunday that the White House had sent them a list of 206 guests.
Kolean, who works in investments, said from what he noticed at the event, Trump campaign members were all masked and socially distant, as were Bedminster staff, who also wore gloves.
