Rep. Duncan Hunter (R-Calif.) has been told to stop using the Marine Corps' emblem and the 1st Marine Division's motto in his campaign literature, Corps officials confirmed.

The Marine Corps Trademark Licensing Office has sent Hunter, a Marine veteran, a cease and desist letter telling him to quit using the Eagle, Globe, and Anchor emblem along with the phrase, "No Better Friend, No Worse Enemy," on a fundraising mailer that accuses his political opponent of having links to terrorism, NBC News first reported on Wednesday.
