Rudy Giuliani, who served as former President Donald Trump’s attorney, has been notified that he is under criminal investigation in Georgia for matters related to the 2020 presidential election.

Giuliani’s lawyers revealed on Monday that they had been informed that he is a “target” in Fulton County District Attorney Fani T. Willis’ investigation into efforts to overturn the election results.

The New York Times reported that prosecutors had questioned witnesses before a special grand jury about remarks that Giuliani made during appearances in front of state legislative panels the month after the 2020 election.

Giuliani tried to delay having to testify before the special grand jury by saying that a recent medical procedure would prevent him from being able to travel.

However, Willis’ office obtained records showing that he had “purchased multiple airline tickets with cash, including tickets to Rome, Italy, and Zurich, Switzerland” for dates that “were after” his “medical procedure.”
