TALLAHASSEE (AP) — U.S. Rep. Vern Buchanan won’t be charged by the Department of Justice, which dropped its investigation over possible campaign finance law violations.

The announcement was made this week by Buchanan’s office. The department was looking into whether Buchanan directed a former business partner at an auto dealership to reimburse employees for political contributions.

The Sarasota Republican is seeking his fourth term in office. His campaign had maintained that Buchanan did nothing wrong.
