(CNN) Representatives for Barack Obama sent a cease-and-desist letter to a Republican super PAC on Wednesday, demanding that they stop airing an ad that uses the former President's words to imply former Vice President Joe Biden supports "plantation politics."

The ad was made by The Committee to Defend the President, a super PAC that works to help President Donald Trump and hurt his Democratic rivals, including Biden. It is slated to air in television stations across South Carolina this week.

The cease-and-desist letter was drafted by Perkins Coie, the law office representing Obama.

"This unauthorized use of President Obama's name, image, likeness, voice and book passage is clearly intended to mislead the target audience of the ad into believing that the passage from the audiobook is a statement that was made by President Barack Obama during his presidency, when it was in fact made by a barber in a completely different context more than 20 years ago," stated the letter written by Patchen M. Haggerty.

He added, "To this end, the Committee to Defend the President must immediately remove this ad ... further the Committee to Defend the President must agree on behalf of itself and all affiliated entities to refrain from future misuse of President Obama's intellectual property or right of publicity."
