Indicating that the Justice Department’s probe of Rep. William Jefferson (D-La.) is continuing, Stephanie Butler, the district director in his New Orleans office, has again been subpoenaed for testimony in the case, his office confirmed Wednesday.

A Jefferson staffer described the subpoena — which was reported on the House floor Wednesday — as “nothing out of the ordinary,” noting that Butler had been subpoenaed to testify before. A year ago, Butler and five other staffers from the office announced that they had received subpoenas to testify before the grand jury investigating the case.

The FBI has said it videotaped Jefferson accepting $100,000 in marked bills from an informant, which allegedly were meant to be used to pay off Nigerian officials in support of the business venture of a Kentucky businessman who was allegedly paying Jefferson for his help. A subsequent search of the lawmaker’s home reportedly turned up $90,000 of the marked cash in Jefferson’s freezer. Jefferson has denied any wrongdoing, but the businessman and a former Jefferson staffer already have pleaded guilty in the case.
