The estate of musician Isaac Hayes will go before a federal judge in Atlanta on Tuesday to press former President Donald Trump to stop playing the soul classic “Hold On, I’m Comin’” at political rallies.

A complaint filed by Georgia attorneys James Walker and Gerald Griggs on Aug. 16 alleges that the Trump campaign has willfully violated the copyright held by Isaac Hayes Enterprises and the estate of the Rock & Roll Hall of Fame performer, who died in 2008.
