Hope Hicks, a counselor and senior adviser to President Donald Trump, has tested positive for COVID-19, Bloomberg and The New York Times reported Thursday.

Hicks, one of Trump’s closest and most trusted aides, traveled on Air Force One with the president to Cleveland for Tuesday’s presidential debate and to Minnesota for a rally on Wednesday, Bloomberg said.

She was photographed leaving Air Force One in Cleveland while not wearing a mask. 

Trump told Fox News on Thursday night that he and first lady Melania Trump have been tested for the coronavirus in response to Hicks’s infection and are waiting on the results.

“Whether we quarantine or whether we have it, I don’t know,” Trump told host Sean Hannity. “I just went for a test, and we’ll see what happens.”

People close to Hicks told Bloomberg that she was experiencing symptoms of the coronavirus. It’s unclear, however, what those symptoms were and for how long she’d been experiencing them. 

White House officials have known since at least Wednesday evening that she had tested positive for the virus, the Times reported.

A White House spokesperson did not confirm Hicks’s positive test when asked, saying only that Trump “takes the health and safety of himself and everyone who works in support of him and the American people very seriously.”

“White House Operations collaborates with the Physician to the President and the White House Military Office to ensure all plans and procedures incorporate current CDC guidance and best practices for limiting COVID-19 exposure to the greatest extent possible both on complex and when the President is traveling,” White House deputy press secretary Judd Deere said.

Hicks, a former model and public relations consultant who previously worked for the Trump Organization, returned to the White House as Trump’s counselor in February after resigning in March 2018 from her role as White House communications director. 

Several White House employees have tested positive for COVID-19 since the pandemic began, including national security adviser Robert O’Brien, Vice President Mike Pence’s press secretary Katie Miller and one of Trump’s personal valets.
