Kimberly Guilfoyle, Donald Trump Jr.’s girlfriend, has tested positive for coronavirus.

Guilfoyle, a former Fox News host who’s serving as a top official of Trump 2020 Victory Finance Committee, was in South Dakota to attend President Donald Trump‘s Fourth of July event at Mt. Rushmore Friday when she was tested positive for the deadly virus.

Guilfoyle was reportedly asymptomatic and didn’t travel with the president.

“Thank you for all the well wishes and prayers,” she tweeted. “I feel good thanks be to God and look forward to a speedy recovery so I can resume working to re-elect [Donald Trump].”

COVID-19 cases have been resurging around the U.S., especially in the southern and western parts of the country, recording about 2.9 million cases.

Despite the warnings and criticisms from health experts, Trump still insists that wearing face masks in public should not be mandatory.
