Civil liberties lawyer turned Donald Trump confidant and media surrogate Alan Dershowitz has registered to lobby for an Israeli billionaire accused of looting Africa’s mineral wealth.

Dershowitz is listed as one of three lobbyists working on the contract between the Freeh Sporkin & Sullivan law firm and Dan Gertler, an Israeli businessman who made his fortune in natural resources. Also lobbying on the account are former FBI Director Louis Freeh, the law firm’s founder, and Gary Apfel, the lawyer who helped convince Trump to commute the fraud conviction of meatpacking magnate Sholom Mordechai Rubashkin.

The trio of lawyers are registered to lobby the Treasury Department’s Office of Foreign Assets Control (OFAC), which handles sanctions. The Trump administration sanctioned Gertler in December 2017 under the Global Magnitsky Human Rights Accountability Act, accusing him of using his “close friendship” with then-President Joseph Kabila to strike “opaque and corrupt mining and oil deals” in the Democratic Republic of the Congo. Six months later, the United States blacklisted another 14 businesses tied to Gertler.

“Between 2010 and 2012 alone, the DRC reportedly lost over $1.36 billion in revenues from the underpricing of mining assets that were sold to offshore companies linked to Gertler,” according to the Treasury Department. “The failure of the DRC to publish the full details of one of the sales prompted the International Monetary Fund to halt loans to the DRC totaling $225 million.”
