Giuliani has not announced his diagnosis. CNN has reached out to him for comment.
Giuliani has been traveling the country, leading the President’s long-shot legal battle to overturn the results of the 2020 presidential election. He was mostly recently at the Georgia Capitol in Atlanta on Thursday to attend a Georgia state Senate hearing on the November election.
The 76-year-old former mayor of New York is considered at high risk for complications from the coronavirus due to his age.
Last month, Giuliani’s son, Andrew, who is a White House staffer, tested positive for Covid-19 after attending a Trump campaign legal team news conference with his father in Washington, DC.
