Jack Abramoff, the onetime Washington insider who went to prison in a lobbying scandal, was charged with a criminal conspiracy related to crypto currency and lobbying disclosure, a U.S. prosecutor said.

Abramoff has agreed to plead guilty and faces as long as five years in prison, San Francisco U.S. Attorney David Anderson said Thursday at a press conference in San Francisco. A second man, from Texas, is pleading not guilty.

In the early 2000s, Abramoff was at the center of a scandal that led to 20 convictions or guilty pleas, including two officials in President George W. Bush’s administration, a member of Congress, congressional aides and nine other lobbyists.
