Jack Abramoff, the uber lobbyist who served prison time last decade after pleading guilty to charges related to illegally plying federal legislators with expensive gifts and trips, is once again facing federal charges. And he’s once again turning to white-collar ace Abbe Lowell of Winston & Strawn to navigate them.

Federal prosecutors in San Francisco and the U.S. Securities and Exchange Commission both announced charges Thursday against Abramoff in an alleged scheme to mislead investors about the legitimacy of a new form of cryptocurrency. Abramoff is being charged alongside Rowland Marcus Andrade, the chief executive officer of NAC Foundation. Andrade claimed to be the creator of AML Bitcoin, a cryptocurrency purportedly designed to prevent money laundering and anonymous use through “biometric technologies.”
