FORT LAUDERDALE, Fla. (AP) — A South Florida attorney who has raised millions for notable politicians nationwide and hobnobs with sports stars and celebrities was removed Tuesday as head of the law firm he co-founded, suspected by his partner, investors and federal investigators of financial wrongdoing in an exotic investment scheme.

Scott Rothstein, 47, was dumped as chief executive officer at Rothstein Rosenfeldt Adler by Broward County Circuit Judge Jeffrey Streitfeld, who named a retired Miami judge as receiver to take control of the 70-lawyer firm's finances.

"He has, for now, relinquished his authority," Streitfeld said at a hearing.

Rothstein drives around in luxury cars, owns three homes and in August purchased the former Gianni Versace mansion in South Beach. Now he is suspected of fabricating a business in which he sold legal settlements to investors, hiding the scheme from the firm's other attorneys and keeping millions of dollars for himself.

Federal prosecutors and the FBI declined comment on whether Rothstein is under investigation. But Kendall Coffey, a former U.S. attorney hired by firm co-founder Stuart Rosenfeldt, said he has turned over his preliminary findings about a possible scam to federal authorities and the FBI has been contacted by several investors.

In court Tuesday, Coffey told the judge he was informed that Rothstein was absent from the hearing because he was meeting "with federal authorities" but declined to get into specifics.

The accusations are reverberating to the state capital in Tallahassee, where the Florida Democratic Party said Tuesday it was returning $200,000 in contributions linked to the firm Rothstein Rosenfeldt Adler, while the state Republican Party said it would also refund about $150,000.
