And now his old counsel is turning against him, accusing him of not paying up all the money he owes them for representing him throughout these his legal battles. Giuliani has already paid the firm — which he employed on a retainer agreement that it alleges he broke — $214,000, with his last payment made on Sept. 14 in the amount of $10,000, according to the filing. In total, the firm has charged him $1.57 million from 2019 to 2023.

“I can’t express how personally hurt I am by what Bob Costello has done,” Giuliani told POLITICO in a statement. “It’s a real shame when lawyers do things like this, and all I will say is that their bill is way in excess to anything approaching legitimate fees.”

Insider first reported the lawsuit on Monday.

While Trump has millions of dollars in various pots to help fund his legal battles, including a notable amount coming from his campaign accounts, the former mayor does not. Since he left office, Giuliani has made money with various consulting and law ventures. But after he helped represent Trump in court as the former president sought to overturn the 2020 vote results, a New York state court suspended his law license. In a potential harbinger for financial troubles, Giuliani put his $6.5 million apartment on the market this summer as his lawyers claimed in court that he is “close to broke.” He currently hosts a podcast called “Common Sense” and a daily radio show.
