ATLANTA (AP) — A British filmmaker who shot interviews with Donald Trump and his inner circle in the final months of the former president’s administration has been subpoenaed to testify in a Georgia investigation into whether Trump and others illegally tried to influence the 2020 election in the state.

Footage shot by Alex Holder includes interviews from the campaign trail, as well as footage shot before and after the Jan. 6, 2021, attack on the U.S. Capitol.

His lawyer, Russell Smith, confirmed Holder will appear before a special grand jury in Atlanta on July 12.
