Eminem isn't here for the GOP appropriating his music after it was revealed that he barred presidential candidate Vivek Ramaswamy from using his music after a video surfaced of Ramaswamy performing "Lose Yourself" at the Iowa State Fair. 

The Detroit icon issued a cease and desist letter to the unlikely winner of the first GOP presidential debates informing him that the use of his music is prohibited moving forward. Per Deadline: "Music rights management service BMI sent Ramaswamy’s campaign a letter notifying them that Marshall Mathers, aka Eminem, had objected to their use of his compositions. (Read the Eminem letter). The BMI attorney, Pamela Williams, also informed them that the Eminem works are being removed from a BMI license agreement with the campaign." 

Interestingly enough, Ramaswamy was said to be a rapper himself during his undergraduate years at Harvard under the stage name Da Vek. He even freestyled on Fox News in July.
