"Wearing a uniform to a partisan political event like this is prohibited," US Army spokesperson Lt. Col. Emanuel Ortiz said in a statement. "The Army follows the Department of Defense's longstanding and well-defined policy regarding political campaigns and elections to avoid the perception of DOD sponsorship, approval or endorsement of any political candidate, campaign or cause."
Two service members, assigned to the 9th Mission Support Command, were seen alongside delegates from American Samoa during the state roll call.
"The composition of that shot was an oversight," a Democratic official told the Hill earlier in the day. "Each state was asked to highlight issues and values that matter most and the American Samoa delegation wanted to highlight their commitment to military service when they filmed their segment."
The US military personnel cannot participate in political events while in uniform.
The Democratic Party platform, which is set to be approved at the convention, states that the party “will never use active duty soldiers as political props, and we will never send military forces to suppress Americans exercising their constitutional rights.”
