The Third Marine Air Wing, based at Miramar Air Station in San Diego, is investigating two Marines who posed in blackface while in uniform in a video posted to social media.
In the video, one of the Marines says the word "blackface," then uses a racist expression often used to describe African-Americans. One of the Marines then puts on his cap and salutes.
Zach Highfield, who appears in the video, originally posted it on Snapchat. Last week the video was posted on Twitter, where commenters called for the Marines to be disciplined and discharged from the Corps.
"We are aware of the post. An investigation has been initiated to determine the facts and circumstances surrounding the content," said Maj. Josef Patterson, spokesman for 3rd Marine Aircraft Wing in a written statement issued Monday.
"Our leaders are committed to maintaining an environment of professionalism, dignity, and respect. Third MAW takes all allegations of discriminatory behavior very seriously as they stand in stark contrast of our core values of honor, courage, and commitment and do not reflect the discipline and professionalism of the Marines and Sailors of 3rd MAW."
