US White House National Security Adviser Robert O'Brien was awarded Corona 19 training.

This is the first time that the White House senior officials have been confirmed by the spread of Corona 19, as the number of corona 19 confirmed in the United States has exceeded 4 million.

Aide O'Brien is considered to be President Trump's closest.

The White House issued a statement, confirming that "the National Security Adviser Robert O'Brien was confirmed by Corona 19," and said, "He is showing mild symptoms and has been self-isolating in a safe place away."

"There is no risk of being exposed to the President or Vice President," he said. "The NSC's work continues uninterrupted."

The White House, however, did not reveal details of the route of infection and how often he had contacted President Trump, Politico, a political media outlet, reported.

CNN broadcaster "O'Brien is the highest official among Trump administration officials who have been confirmed by Corona19," he said. It is unclear when O'Brien was the last time he met Trump.

CNN said the two of them appeared together at the official event when they visited the South Miami headquarters on the 10th of last month.

Earlier, Bloomberg reported citing sources that O'Brien was admitted to be corona19-positive and has not been in the White House office since late last week.

Adviser O'Brien attended a family event and was infected with Corona 19, and was reportedly in isolation from his home.

Bloomberg News Agency advisers O'Brien and senior staff at the NSC have been screened daily for Corona19 and his offices are located at the end of the corridors of the President's office and Vice President Mike Pence's office.

Adviser O'Brien is the highest person in the history of Corona 19 around the president, and the White House has become even more emergency.

Earlier in May, some people in the White House, including a spokesman for Vice President Kate Miller, were infected with Corona19.

Despite the White House's explanation that there is no risk of exposure to President Trump as the security adviser overseeing the White House NSC and overseeing the White House NSC is positive, the wave is expected to increase as concerns about the spread of Corona 19 in the White House increase. .

Some voices have raised concerns about the security gap.
