A hand-drawn swastika discovered inside the U.S. Coast Guard’s main recruit training base in Cape May, New Jersey, has been removed and referred to the Coast Guard Investigative Service for a formal investigation, the service confirmed.

According to reporting from The Washington Post, a Coast Guard instructor spotted the symbol late last week on a men’s bathroom wall. The Coast Guard said it moved quickly to erase the graffiti, while investigators work to identify who drew it and whether additional incidents are connected.

Commandant Adm. Kevin Lunday traveled to Cape May and addressed roughly 900 recruits and staff, issuing a blunt warning aimed at anyone trying to import extremist ideology into the ranks: “Anyone who adheres to or advances hate or extremist ideology, get out. Leave.”

The location matters. Training Center Cape May is the Coast Guard’s sole enlisted accession point, essentially the front door for the entire enlisted force, and recruit training is an eight-week pipeline that runs year-round. A hate symbol in that environment is a direct attempt to intimidate and normalize antisemitism at the point where new service members are being shaped.

In recent months, the Coast Guard faced backlash over language in a workplace harassment manual that described swastikas and nooses as “potentially divisive,” prompting public outcry and congressional pressure, including a hold on Lunday’s nomination by Sens. Tammy Duckworth and Jacky Rosen until the guidance was tightened.
