The Army is investigating why two junior enlisted soldiers in uniform were flanking the Democratic delegates of American Samoa during Tuesday night's video roll call at the Democratic National Convention.

A Democratic National Convention official told ABC News on Wednesday that "the composition of that shot was an oversight."

The sight of the uniformed soldiers had raised eyebrows because U.S. military personnel are not supposed to participate in political events while in uniform. "We're grateful for the participation of delegations and state volunteers in all 57 states and territories -- they made the inspiring roll call we saw last night possible," the official told ABC News. "The composition of that shot was an oversight."

"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 official said.

Regardless of the intent the presence of the uniformed soldiers has triggered an Army investigation because uniformed military personnel are not allowed to participate in political events.

‘The Army is investigating two Soldiers from the 9th Mission Support Command who appeared in uniform during the Democratic National Convention on Aug.18," said an Army statement. "Wearing a uniform to a partisan political event like this is prohibited."

"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," it continued.

All American military personnel, active duty members and reservists are instructed to remain apolitical during political campaigns.
