National security adviser Robert O'Brien returned to the White House on Tuesday after recovering from a mild case of COVID-19, AP reports.

Why it matters: O'Brien was the closest official to President Trump to test positive for the coronavirus on July 27.

What they're saying: "He has been cleared by doctors after two negative tests for the virus, and has been asymptomatic for over a week,” National Security Council spokesman John Ullyot told AP.

  • Ullyot added that O’Brien’s return was consistent with advice from the White House medical unit and the Centers for Disease Control and Prevention.

Meanwhile: The White House announced Monday that randomized coronavirus testing for Trump's executive office staff would be put in place to protect everyone at the complex.
