Washington ? A U.S. House commission threw out Wednesday a complaint against Republican Rep. Todd Tiahrt lodged by his re-election challenger, Democrat Carlos Nolla.

Nolla accused Tiahrt of misusing taxpayer money by producing and mailing out a brochure that Nolla said looked too much like campaign literature.

The flier, which was about the House-passed prescription drug benefit plan, opened with: “Just what the doctor ordered … Prescription drug reform from Congressman Todd Tiahrt.”

The decision came from the top two lawmakers on the U.S. House Commission on Congressional Mailing Standards. The panel’s Republican chairman, Rep. Bob Ney of Ohio, said Wednesday he and the panel’s top Democrat, Rep. Steny Hoyer of Maryland, had agreed to dismiss the complaint.

At issue are the regulations that govern “franking,” a name for the system of sending mail to a lawmaker’s constituents. Ney said in his decision that staffers for the bipartisan commission reviewed the flier carefully before Tiahrt mailed it.
