Trump’s National Security Adviser, Robert O’Brien, tested positive for the virus.

President Trump’s National Security Adviser, Robert C. O’Brien, has tested positive for the coronavirus, the White House said on Monday, making him the most senior White House official known to have contracted the virus.

In a statement, the White House said that Mr. O’Brien “has mild symptoms” and is working remotely from “a secure location off-site.”

“There is no risk of exposure to the president or the vice president. The work of the National Security Council continues uninterrupted,” the statement said.

Mr. O’Brien typically works from a West Wing office that is steps away from the Oval Office. It is unclear when he was last in contact with Mr. Trump, although he joined him on a July 10 trip to Florida. Mr. O’Brien traveled to Paris in mid-July to meet with several of his European counterparts. It was unclear whether he became infected before that trip, and the White House statement did not provide further details.

Senior White House aides are tested regularly for the virus, as is Mr. Trump. Mr. O’Brien assumed his job in September of last year, succeeding John R. Bolton, who resigned after mounting differences with the president.

Mr. O’Brien is the latest of several White House staffers and others in the president’s orbit who have tested positive for the virus. They include a military officer who works as a presidential valet at the White House and Vice President Mike Pence’s press secretary, Katie Miller, both of whom tested positive in early May. Last week, the White House closed two cafeterias in its extended complex after an employee tested positive.

Earlier in the month, Mr. Pence postponed a planned trip to Arizona after members of his Secret Service detail tested positive or showed symptoms of the virus. Kimberly Guilfoyle, a former Fox News commentator who is dating Donald Trump, Jr., also contracted the virus, as did several Trump campaign advance staffers who helped to arrange his June rally in Tulsa, Oklahoma.
