White House Press Secretary Kayleigh McEnany announced Monday that she tested positive for coronavirus.

Why it matters: She is the latest member of President Trump's inner circle to be diagnosed with the illness over the last few days.

• McEnany said that she is "experiencing no symptoms" in her announcement.
• She added that "no reporters, producers or members of the press are listed as close contacts by the White House Medical Unit."

Between the lines: McEnany's positive test underscores a unique challenge for the White House as it battles its ongoing coronavirus outbreak because it may take days for people to test positive.

Worth noting: McEnany did not wear a mask while speaking to reporters as recently as Sunday.

• Three journalists working at the White House already tested positive last week.

What she's saying: "As an essential worker, I have worked diligently to provide needed information to the American people at this time. With my recent positive test, I will begin the quarantine process and will continue working on behalf of the American people remotely," she wrote on Twitter.
