SAN DIEGO — The U.S. Marine Corps has asked U.S. Rep. Duncan Hunter to stop using its trademarked emblem and slogan on his fundraising mailers.

The San Diego Union-Tribune says the service wrote Hunter a letter Tuesday asking him to immediately stop using the USMC Eagle, Globe and Anchor emblem and the phrase "No Better Friend, No Worse Enemy" on all campaign materials.

The letter says the Republican lawmaker is welcome to state he's a Marine veteran and use an alternative logo.

Spokesman Michael Harrison says Hunter is disappointed but the campaign is complying with the request.

Harrison released a statement to News 8 on the matter that read in part: 

"Congressman Hunter is a Marine combat veteran, he's proud to be a Marine and to reflect this, our design team created an image to utilize the globe and anchor.  The Marine Corps contacted Congressman Hunter's campaign expressing their concerns and requesting that their copyrighted logo not be utilized in any campaign material and provided alternate resources that we may use.  Congressman Hunter's campaign immediately complied and is taking all appropriate measures to ensure this matter is addressed appropriately and thoroughly."

Hunter is fighting for reelection in 2020 while facing criminal charges that allege he and his wife used $250,000 in campaign donations for personal expenses. His wife has pleaded guilty and agreed to testify against him.
