It has said it is a nonprofit “dedicated to uniting Americans around the nation’s 250th anniversary”.
Freedom 250 was launched last year by the Trump administration and has scheduled events across the country to celebrate the nation’s semiquincentennial.
Its CEO Keith Krach was appointed by President Donald Trump to lead the organisation.
Rappers Morris Day and Young MC were first to announce they would not be participating.
Young MC, best know for his 1989 hit Bust a move, said on his social media that artists were not told about any “political involvement with the event” and that he looked forward to performing in DC in the future at an event that “is not so politically charged”.
Morris Day posted an image on Instagram with the text “Contrary To Rumor, Morris Day & The Time Will Not Be Performing At The ‘GREAT AMERICAN STATE FAIR'”. The post was captioned “It’s A No For Me.”
The next day, other artists followed suit.
“The Commodores will not be performing at the Great American State Fair,” the group posted on their social media accounts. “Our music has always been our voice and we choose not to publicly affiliate with any single political party. We support the betterment of all Americans.”
Singer McBride said in a statement on X that she was “presented with an opportunity to perform at a nonpartisan event but that turned out to be misleading”.
In a lengthy statement on social media on Friday morning, Bret Michaels also said: “Unfortunately what was presented to us as a celebration of our country has evolved into something much more divisive than what I agreed to be a part of.”
He also cited safety concerns.
Rappers Flo Rida and Vanilla Ice, however, are still slated to perform.
