WATCH: More Musicians Threaten Trump Campaign With Legal Action

The legendary supergroup ABBA and rocker Jack White are the latest musical acts to speak out against Donald Trump's campaign for using their music without their permission.

ABBA--which recently mounted a comeback--told the Associated Press that the band had only recently become aware of the "unauthorized use of their music and videos at a Trump event through videos that appeared online. 

ABBA and its representatives have "promptly requested the removal and deletion of such content. No request has been received; therefore, no permission or license has been granted," according to the AP.

A spokesman for the Trump campaign said it had obtained a license. “The campaign had a license to play ABBA music through our agreement with BMI and ASCAP,” the spokesperson told the AP.

The campaign might have an agreement to license songs via BMI and ASCAP, but they still have to obtain artists' permission when their songs are used to raise money or promote a brand or other entity.

Rocker Jack White took a saltier approach when he learned Trump campaign official Margo Martin posted a video using “Seven Nation Army” from White’s former band The White Stripes.

"Oh....Don't even think about using my music you fascists," White wrote on Instagram. "Lawsuit coming from my lawyers about this (to add to your 5 thousand others.) Have a great day at work today Margo Martin." -Jack White

Foo Fighters announced last week that they're seeking legal action against Trump after their song "My Hero" was used to introduce Robert F. Kennedy Jr at a rally. The band will also donate any royalties from that usage to the Harris/Walz campaign.

Dolly Parton is also said to be considering legal action after Trump used her song "Jolene" without permission.

The estate of Isaac Hayes will face Trump's legal team on September 3rd after being granted an emergency hearing over Trump's use of "Hold On, I'm Coming."
