Donald Trump Jr.’s girlfriend, Kimberly Guilfoyle, who is also a senior campaign adviser, tested positive for COVID-19 before the president’s event at Mount Rushmore in South Dakota on Friday night, The New York Times reported. The president’s son tested negative for the virus, and he and Guilfoyle skipped the extravaganza and plan to drive back to the East Coast, Times reporter Maggie Haberman tweeted. A person familiar with the situation told the newspaper that Guilfoyle and Don Jr. did not fly to South Dakota on Air Force One and had no contact with President Trump.

A spokesperson for Rep. Greg Gianforte (R-MT), who is running for governor of Montana, said the congressman’s wife, Susan, and running mate, Kristen Juras, attended an event with Guilfoyle on Tuesday. The trio would self-quarantine and suspend in-person campaign events “out of an abundance of caution,” the statement said.
