Kimberly Guilfoyle, a senior Trump campaign official and friend of Donald Trump Jr., was tested positive for coronavirus in South Dakota on Friday, according to a person familiar with the situation.
Trump Jr., the oldest son of President Donald Trump, has tested negative, the person said.
Neither Trump Jr. nor Guilfoyle traveled with the President of Air Force One when the President went to Mount Rushmore on the weekend of July 4, the person said.
Both wanted to participate, but never made it to the construction site. Comments from Guilfoyle and Trump Jr. were not immediately returned on Friday evening.
Guilfoyle is expected to return to the east coast to avoid interactions with other people, said two people familiar with the matter.
The White House says Trump is tested for the corona virus daily.
The New York Times reported for the first time that Guilfoyle tested positive.
It was developed on a day when, according to NBC News, more than 53,000 new cases of COVID-19 were reported in the United States.
Guilfoyle, chairman of the Trump Victory Finance Committee, spoke on June 23 at Trump's rally on June 20 in Tulsa, Oklahoma, and in the introductory program prior to Trump's speech in Phoenix, Arizona.
However, it is unknown when or where she was exposed to the coronavirus that causes the COVID-19 disease.
Although the location of the exposure is not known, several participants have tested positive for the virus since the Tulsa rally, including a journalist and at least two members of the campaign's advance team.
In addition, six campaign employees tested positive hours before the rally, but were not present.
It was announced on Thursday that former presidential candidate Herman Cain, who participated in the Tulsa rally, tested positive for COVID-19.
He received the positive result on Monday and on Wednesday developed symptoms that were so severe that he had to go to the hospital posted on his Twitter account said.
The 74-year-old Cain didn't need a respirator and was awake and alert in a hospital near Atlanta.
It is not known when Cain was exposed to, or became infected with, the disease.
Trump's campaign said in a statement on Thursday that Trump had not met Cain at the Tulsa rally.
According to NBC News, there were more than 2.7 million cases of COVID-19 in the United States with more than 130,000 deaths related to the disease.
Cases have increased in a number of states, and 19 states have either postponed or halted plans to reopen due to the disease.
