The House Ethics Committee has closed an investigation into Congressman G.K. Butterfield and five other members of congress.
Butterfield spokesman Ken Lewis says the panel found no evidence that the congressmen violated any rule or was guilty of any misconduct.
Butterfield, a Democrat from Wilson, was being investigated after the Wall Street Journal reported he and the others had used daily cash stipends to cover unauthorized expenses. Lawmakers are given up to $250 a day when traveling overseas to cover food and other expenses.
The investigation began last summer.
