BOISE, Idaho (AP) — Former U.S. Senator Larry Craig is appealing a ruling ordering him to pay nearly $242,000 to the U.S. Treasury for improperly using campaign funds to pay for legal expenses following his 2007 airport bathroom sex sting arrest.

Craig filed the one-page appeal Monday to the U.S. Court of Appeals for the District of Columbia Circuit in Washington, D.C. A federal judge ruled in September that Craig illegally converted campaign money for personal expenses while trying to withdraw his guilty plea to one count of disorderly conduct.

An undercover police officer arrested the Idaho Republican at the Minneapolis-St. Paul International Airport. The officer said Craig signaled under the stall that he wanted sex.
