Rudy Giuliani, who visited Atlanta days ago, tests positive for COVID

Giuliani was admitted Sunday to Georgetown University Medical Center in Washington, according to multiple media reports.

Giuliani, the former mayor of New York City, was in Atlanta on Thursday for a hearing before state senators on a Judiciary subcommittee at the Capitol. Videos show he did not wear a mask in the committee room, which was filled with elected officials, witnesses and journalists.

He was in “close proximity to senators, Senate staff, members of the media and the general public,” state Sen. William Ligon, the chairman of the subcommittee, said in a statement Sunday evening.

Anyone who came into “close contact” with Giuliani should “take every precaution and follow all requisite guidelines to ensure their health and safety.”

Centers for Disease Control and Prevention guidelines state that anyone who had contact with a person who tested positive for COVID-19 should quarantine for 14 days.

At Thursday’s hearing, Giuliani and other Trump attorneys brought a parade of witnesses who expressed doubts about the integrity of the election in Georgia, though there is no evidence of widespread voter fraud during the election.

Among other things, they repeated a conspiracy theory that the state’s new voting system was designed to switch votes — a claim disputed by the company that produced the system and by Georgia officials.

They also showed video of Fulton County vote-counting they say showed suitcases of ballots being counted in secret after Republican poll monitors were sent home. The county and the secretary of state have disputed that account.

Giuliani, 76, also attended an election hearing in Michigan last week.
