It’s now drawing in a duo familiar to anyone who has followed past Washington imbroglios: conservative lawyers and GOP operatives Joe diGenova and his wife, Victoria Toensing. And the scandal is beginning to reveal the opaque agendas of a pair of Ukrainian oligarchs whose legal troubles have led them to seek favors in Washington.

DiGenova and Toensing, who played major roles in the Bill Clinton dramas of the 1990s and resurfaced amid Hillary Clinton’s 2016 campaign, have signed up to represent Dmitry Firtash, a Ukrainian gas magnate who currently resides in Vienna pending extradition to the U.S. to face bribery charges…

For Firtash — who is fighting extradition from Austria to the U.S. to face bribery charges — his involvement began at least as early as July, when he parted ways with Lanny Davis, the lawyer who guided Bill Clinton through a variety of investigations and now represents Michael Cohen, the former Trump fixer who confessed to tax evasion, campaign finance violations and lying to Congress, among other crimes.
