Gabbard, like other politicians with military experience, often uses images and video of herself in uniform in campaign ads. But the U.S. Department of Defense has policies in place aimed at making sure those ads are not seen as an endorsement from any branch of the military.

Campaign material must include a “prominent and clearly displayed disclaimer” that the ad or image is not a military endorsement. Candidates are also forbidden from using images of themselves in uniform as the primary graphic in campaign material.

Gabbard’s campaign, as of Monday afternoon, appeared to have already removed a video of Gabbard in uniform on the VoteTulsi Facebook page that the National Guard had flagged. Her campaign also added a disclaimer to the website’s banner image — a photograph of Gabbard in uniform in a veterans cemetery — that notes the image does not imply an endorsement by the military. However, the disclaimer is visible only if one clicks on the photograph.
