President Donald Trump announced Sunday that former New York Mayor Rudy Giuliani, who has led his efforts to overturn last month's election, has tested positive for Covid-19.
"Get better soon Rudy, we will carry on!!!" Trump wrote on Twitter.
Giuliani, Trump's personal attorney, has crisscrossed the country in recent days pushing Trump's unverified claims of voter fraud. He most recently appeared without a mask during a meeting with Georgia lawmakers Thursday.
Giuliani did not respond to a request for comment from NBC News. It was not yet clear where Giuliani was Sunday afternoon or whether he was suffering from any symptoms. Earlier Sunday, he was interviewed on Fox News.
On Monday morning, a source familiar with Giuliani’s diagnosis said that he is at MedStar Georgetown University Hospital in northwest Washington, D.C., feeling mild symptoms so far. The hospital has not returned a request for comment.
In a tweet posted Sunday evening, Giuliani said he was "getting great care and feeling good."
At 76, Giuliani is considered to be at high risk for complications stemming from the virus.
Trump later retweeted a call for Americans to pray for Giuliani.
Giuliani's son, Andrew Giuliani, tweeted Sunday evening that his father "is resting, getting great care and feeling well. Thank you to all the friends who have reached out concerned about his well being."
Giuliani had dodged the virus for weeks as multiple people in his orbit tested positive.
Giuliani appeared at events such as Trump's election night party at the White House and a news conference alongside Trump's legal team, and most recently he attended election-related meetings with state lawmakers in Pennsylvania, Arizona, Michigan and Georgia. Each event featured attendees without masks, including Giuliani.
Some at the events, including Giuliani's son, tested positive for the virus afterward. In addition, Christianné Allen, his spokesperson, tested positive late last month and had been quarantining after the mid-November news conference, Salon reported.
Giuliani is the 20th person close to Trump who has tested positive for the virus since the election night party, according to an NBC News count.
