Former President Donald Trump and the 18 others charged in recent Georgia indictment are expected to turn themselves in, according to the Fulton County Sheriff's Office.

"At this point, based on guidance received from the District Attorney’s Office and presiding judge, it is expected that all 19 defendants named in the indictment will be booked at the Rice Street Jail," the sheriff's office said.

Trump and the other defendants have until Aug. 25 to voluntarily surrender to authorities.

As an upstart chief prosecutor in perhaps the most prestigious legal office in the country, Rudy Giuliani in the mid-1980s made use of a novel way to quell the scourge of New York organized crime -- leveraging a brand new, little-known federal statute called Racketeer Influenced and Corrupt Organizations.

Using RICO, as it's known, Giuliani managed to charge dozens of mobsters with seemingly unrelated crimes, all under the umbrella of one overarching scheme. At the time, it was a revolutionary use of federal law and it later served as a model for state and federal prosecutors around the country.

As U.S. attorney for the Southern District of New York, Giuliani's successful prosecutions of New York's storied crime families made him a media darling and launched Giuliani's political career. But now, four decades later, Giuliani finds himself on the other side of his own legal legacy -- facing Georgia state criminal RICO charges in the Fulton County district attorney's case against his longtime boss, former President Donald Trump, and 18 of his allies.

"This is perfect, perfect irony," said Anthony Cardinale, a veteran defense attorney who represented "Fat Tony" Salerno, the former head of the Genovese crime family, in 1986. "Giuliani is going to be sitting in a courtroom, pray to God ... 40 years after he started bringing these exact types of cases."

Georgia Gov. Brian Kemp, who Donald Trump allegedly pressured to overturn the 2020 election results in the state, is defending the state's election process in response to the Fulton County indictment and Trump’s Truth Social post announcing a press conference on alleged voter fraud in Georgia.

"The 2020 election in Georgia was not stolen," Kemp said in a statement. "For nearly three years now, anyone with evidence of fraud has failed to come forward -- under oath -- and prove anything in a court of law. Our elections in Georgia are secure, accessible, and fair and will continue to be as long as I am governor."

He added, "The future of our country is at stake in 2024 and that must be our focus."

In addition to the 19 defendants listed in the indictment, as many as 30 unindicted co-conspirators were involved in the criminal scheme, according to prosecutors.

"The Defendants, as well as others not named as defendants, unlawfully conspired and endeavored to conduct and participate in a criminal enterprise in Fulton County, Georgia, and elsewhere," the indictment says.

The indictment says "several" of the defendants made false statements to Georgia officials, including the secretary of state and Speaker of the House of Representatives, and "corruptly solicited [them] … to violate their oaths to the Georgia Constitution and to the United States Constitution by unlawfully changing the outcomes of the November 3, 2020, presidential election in favor of Donald Trump."
