The American Legion has asked the campaign of Democratic presidential candidate Bernie Sanders to "cease and desist" from using the organization's emblem in campaign fliers.
The American Legion wrote to Sanders' Senate office that it did not have permission to use the emblem in his campaign fliers.
Sanders' campaign didn't immediately return a request seeking comment.
The American Legion has twice complained to Sanders officials since Jan. 22 about the use of the emblem in campaign materials. A Feb. 1 letter from the American Legion obtained by The Associated Press warns that "any further communication about it will be through our trademark attorney in the appropriate forum."
An earlier report in a New Hampshire paper said that Sanders had used the images of pastors and veterans in his fliers.
