Rudolph W. Giuliani, President Trump’s personal lawyer, has contracted the coronavirus, the president said Sunday in a tweet.

“.@RudyGiuliani, by far the greatest mayor in the history of NYC, and who has been working tirelessly exposing the most corrupt election (by far!) in the history of the USA, has tested positive for the China Virus,” Trump tweeted Sunday afternoon. “Get better soon Rudy, we will carry on!!!”

Giuliani traveled to states including Michigan and Georgia last week and met indoors with state legislators in an effort to persuade them to overturn President-elect Joe Biden’s victory. Videos of the appearances showed Giuliani was not wearing a mask during the meetings.

Hours before Trump’s tweet, Giuliani appeared on Fox News’s “Sunday Morning Futures,” where he repeated the president’s false claims of election fraud.
