Rudy Giuliani's former colleagues reflect on his path from law-and-order champion to RICO defendant: "A tragedy"

Waving his glasses in front of his face while recording his YouTube show on Tuesday, Rudy Giuliani taunted the prosecutor who had just charged him with racketeering.

"You're screwed, Fani. Giuliani got new glasses. Ha! And he's like five times the lawyer … five times the lawyer you are? How can you? No. Well, you can't multiply by zero," Giuliani said.

Giuliani was one of 19 people, including former President Donald Trump, indicted in Georgia Monday in a broad racketeering case focused on their efforts to overturn the state's 2020 presidential election results. On his YouTube show Tuesday, he echoed the irony many of his former colleagues recalled in interviews in recent days, having watched Giuliani transform from a hard-charging federal prosecutor-turned-mayor — known for his tough-on-crime braggadocio — to defendant in a case painting him as a central figure in a "criminal enterprise" bent on overthrowing a president-elect.
