Queen is expressing frustration at what they say is the continued unauthorized use of their material in the Donald Trump campaign.

The Republican presidential nominee used their 1977 hit, “We are the Champions,” during his Tuesday night appearance at the Republican National Convention.

"We are frustrated by the repeated unauthorized use of the song after a previous request to desist, which has obviously been ignored by Mr. Trump and his campaign," the band said in a statement via Sony/ATV Music Publishing.

"Queen does not want its music associated with any mainstream or political debate in any country. Nor does Queen want 'We are the Champions' to be used as an endorsement of Mr. Trump and the political views of the Republican Party. We trust, hope and expect that Mr. Trump and his campaign will respect these wishes moving forward."

Last month, the band publicly denounced the use of their anthem when it was played during a Trump victory speech.

At the time, Queen guitarist Brian May wrote on his website, "This is not an official Queen statement, but I can confirm that permission to use the track was neither sought nor given. We are taking advice on what steps we can take to ensure this use does not continue. Regardless of our views on Mr. Trump's platform, it has always been against our policy to allow Queen music to be used as a political campaigning tool. Our music embodies our own dreams and beliefs, but it is for all who care to listen and enjoy."

Queen isn't the only band whose music the Trump campaign has appropriated without permission – Aerosmith, R.E.M. and Neil Young have also expressed their anger.

Last fall, after Trump appeared at a rally with R.E.M.'s "It's the End of the World as We Know It (And I Feel Fine)" playing behind him, the band's Mike Mills commented on Twitter, "Personally, I think the Orange Clown will do anything for attention. I hate giving it to him."
