Roger Stillwell, the desk officer for the Mariana Islands at the U.S. Department of the Interior who dealt closely with disgraced lobbyist Jack Abramoff, is expected to plead guilty to a misdemeanor count of false certification, his attorney confirmed Wednesday.

Department of Justice officials charged Stillwell, 65, with filing a financial-disclosure report for fiscal year 2003 that “falsely certified that he did not receive reportable gifts from a prohibited source,” according to a document filed June 27 in the U.S. District Court for the District of Columbia.
