Kimberly Guilfoyle tests positive for coronavirus

Kimberly Guilfoyle, a senior Trump campaign official and Donald Trump Jr.’s girlfriend, tested positive for coronavirus while in South Dakota, a person familiar with the situation said Friday.

Trump Jr., the eldest son of President Donald Trump, tested negative, the person said.

Neither Trump Jr. nor Guilfoyle traveled with the president on Air Force One as the president went to Mount Rushmore for a July 4th weekend celebration, the person said.

They both planned to attend but never made it to the site. Requests for comment from Guilfoyle and Trump Jr. were not immediately returned Friday night.

Guilfoyle is expected to drive back to the East Coast to avoid interactions with other people, two people familiar with the matter said.

The White House says Trump is tested for the coronavirus daily.

The development occurred on a day in which there were more than 53,000 new cases of COVID-19 reported across the United States, according to NBC News counts.

Guilfoyle, who is Trump Victory Finance Committee chair, spoke at Trump's June 20 rally in Tulsa, Oklahoma, and in the introductory program ahead of Trump's remarks in Phoenix, Arizona, on June 23.

But it is unknown when or where she was exposed to the coronavirus that causes the disease COVID-19.
