U.S. Attorney James Santelle is under investigation on accusations that he misused the government-assigned credit card and violated a law barring federal employees from some political activities, The Milwaukee Journal Sentinel reports.
The Department of Justice is leading the investigation, which started more than a year ago following a routine audit.
Investigators are trying to determine whether the credit card was used for non-official use, like food.
Santelle, who works in Milwaukee, declined to comment.
“I am not in a position to comment other than those matters are both with the Department of Justice,” he said Monday.
