National Security Council spokeswoman Adrian Watson announced that US National Security Adviser Jake Sullivan tested positive for Covid-19 a week before he was scheduled to travel with President Joe Biden to the G7 summit.

Watson’s spokeswoman said Sullivan was not in close contact with the president and showed no symptoms of illness. She added that this was the first time Sullivan had contracted Covid.

The White House said Sullivan met at the White House on Friday with Senegalese Foreign Minister Isata Tal Sall. The White House added that it personally met with China’s top diplomat Yang Jiechi in Luxembourg for four and a half hours on Monday.

It was not immediately clear whether the results of medical tests would affect Sullivan’s travel plans.

The White House announced last week that Biden would travel to southern Germany for the G7 summit and travel to Spain for the NATO summit at the end of June.
