On August 3, 2012, the Associated Press reported that Craig, who is being sued by the Federal Elections Commission (FEC) for allegedly misusing more than $200,000 in campaign funds for his legal defense following his 2007 arrest in a bathroom sex sting, seeks to fend off the charges by arguing that the incident was part of his official Senate business. Craig asserts that he was travelling between Idaho and the nation's capital for work and cites a Senate rule which include all charges for meals, lodging, hotel fans, cleaning, pressing of clothing—and bathrooms—as reimbursable per diem expenses. "Not only was the trip itself constitutionally required, but Senate rules sanction reimbursement for any cost relating to a senator's use of a bathroom while on official travel," wrote Craig’s lawyer in documents filed on August 2, 2012.

In 2011, Craig lobbied Congress to remove the gray wolf from protection under the Endangered Species Act. The former U.S. Senator’s client, Sportsmen for Fish and Wildlife, wanted the gray wolf de-listed because of concern that a recovered wolf population would eat big game animals prized by hunters. Once common in throughout North America, the gray wolf is now extinct in all but a few locations in the United States.

In an August 2007 letter to a constituent who asked about the military’s “Don’t Ask, Don’t Tell” policy concerning homosexuality, Craig wrote, “It is unacceptable to risk the lives of American soldiers and sailors merely to accommodate the sexual lifestyles of certain individuals.”

In a video appearance at a 2007 “Friends of the NRA” dinner, Craig suggested that it was plausible that total firearm confiscation could occur in the United States and said, “When the government is the sole owner of firearms, you and I then become the subjects of a government, or the victims of a government, and not the free citizen that this country has been built on.”

In the wake of Hurricane Katrina, Craig was hesitant to provide federal funds to aid the recovery. Preferring instead that the damaged areas of New Orleans be abandoned, he said, “Fraud is in the culture of Iraqis. I believe that is true in the state of Louisiana as well.” Craig suggested that the Lower Ninth Ward be turned “back to what it was, a wetland.”

In a 1999 appearance on Meet the Press, Craig criticized then-President Bill Clinton for having an extramarital affair, calling Clinton “a nasty, bad, naughty boy”.

Craig urged his sexual partners to keep quiet by using threats, reportedly telling one man in 1986, “I can buy and sell your ass a thousand times over. You were never here.”
