The arrest warrant of Hallandale Beach Mayor Joy Cooper details how a once-prominent Broward attorney and lobbyist used “Russian organizations” charging up to $1,000 to make political kickbacks appear as legitimate campaign contributions.

The ex-lawyer at the center of the scandal is former high-powered lobbyist Alan Koslow, who U.S. District Judge William Dimitrouleas sentenced in November 2016 to one year and a day in prison for money laundering. He’d lost his law license about a month earlier, after an uncontested petition for disciplinary revocation before the Florida Supreme Court.
