Story highlights Great America Alliance is running an ad that quotes Obama narrating his autobiographical book "Dreams From My Father."

The ad, however, does not mention that Obama is actually quoting someone else in the passage.

(CNN) An outside group that supports President Donald Trump is running a radio ad in Atlanta ahead of Georgia's special election Tuesday that takes the voice of former President Barack Obama out of context to make the argument that Democrats take black voters for granted.

Great America Alliance, a pro-Trump non-profit group that previously ran ads attacking former FBI director James Comey during his testimony, is running an ad that quotes Obama narrating his autobiographical book "Dreams From My Father." The ad, however, does not mention that in the selected passage, Obama is actually quoting someone else who is speaking about the black community and Chicago politics before the early 1980s.

The ad begins with narration from conservative activist Autry Pruitt.

"Hi, my name is Autry Pruitt, a fellow black American working hard every day, just like you. It may seem out of season, but all of a sudden, Democratic politicians have started coming around again. We normally only see them every other November, swarming around and making promises to get our vote. But nothing ever changes for us, does it? Here's what President Barack Obama had to say about it."

Then Obama can be heard saying, "Plantation politics. Black people in the worst jobs. The worst housing. Police brutality rampant. But when the so-called black committeemen came around election time, we'd all line up and vote the straight Democratic ticket. Sell our souls for a Christmas turkey."
