Attorneys of the former president of the United States, Barack Obama, have ordered a pro-Trump group to stop promoting an ad which reportedly uses Obama's own words to slam presidential candidate, Joe Biden.

Obama's lawyers will file a cease-and-desist letter if they don't stop:

"This despicable ad is straight out of the Republican disinformation playbook, and it's clearly designed to suppress turnout among minority voters in South Carolina by taking President Obama's voice out of context and twisting his words to mislead viewers," Obama's spokeswoman, Katie Hill, said in a statement, per The Hill. 

"In the interest of truth in advertising, we are calling on TV stations to take this ad down and stop playing into the hands of bad actors who seek to sow division and confusion among the electorate."

The ad includes sections from Obama's memoir, Dreams from My Father to urge the state's Black voters to vote against Biden.

"Joe Biden promised to help our community. It was a lie. Here's President Obama," the ad begins.

"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," Obama says in the book -- this was included in the ad.

Biden's campaign spokesman released a statement slamming the ads:

"Donald Trump and his allies are absolutely terrified that Joe Biden will defeat him in November. Trump even got himself impeached by trying to force another country to lie about the vice president," Andrew Bates said in the statement. "This latest intervention in the Democratic primary is one of the most desperate yet, a despicable torrent of misinformation by the president's lackeys."
