The National Guard deployment in Washington, D.C., could be extended into the summer of 2026, according to a new court filing and emails of National Guard leaders obtained by ABC News.

The Office of the Attorney General in D.C. is suing the federal government, saying that the deployment of the National Guard on the streets of D.C. is unlawful, and that it's causing irreparable harm in the city now turning for president.

In a suit filed in federal court, attorneys for Sam O’Hara, 35, of Washington, said he would regularly protest the National Guard’s presence by walking several feet behind them and playing the march also known as "Darth Vader's Theme," from "The Empire Strikes Back," the second film in the "Star Wars" series, when he saw them in the community.

Sam O'Hara claims that his First and Fourth Amendment rights were violated, and that he was subjected to false arrest and battery

The lawsuit filed by the ACLU says the Ohio National Guard member and several other DC-area police officers violated man's First Amendment rights.

Sam O’Hara, a Washington, DC resident, says he was briefly detained by police after he played the Darth Vader theme song in protest of the National Guard. O’Hara is now filing a lawsuit claiming his First Amendment rights were violated.

The protester played “The Imperial March,” a song associated with Darth Vader, while walking behind the troops.
