David Bossie, a former deputy campiagn manager for Donald Trump, has apologised for making a racially fueled remark on American television.
Mr Bossie, who is a close ally of the President, appeared on American morning television show Fox and Friends along side Democratic strategist Joel Payne on Sunday.
In the heated debate, the two discussed racial slurs and connotations made by previous governments.
"You're out of your cotton-picking mind," Mr Bossie told Mr Payne, disagreeing with one of his points.
"Cotton-picking mind?" Payne, who is African-American, replied.
"Brother, let me tell you something: I got some relatives who picked cotton and I'm not going to sit here and allow you to attack me like that on TV. I'm not out of my cotton-picking mind."
Fox and Friends host Ed Henry later said he did not agree with the phrase, The Guardian reports.
"It was obviously offensive, and these debates get fiery that's unfortunate, " Mr Henry said.
"We like to have honest and spirited debates but not phrases like that, obviously. And so I will just leave it at that."
Mr Bossie posted an apology on Twitter.
"During a heated segment on Fox and Friends today, I should have chosen my words more carefully and never used the offensive phrase that I did. I apologise to Joel Payne, Fox News and its viewers," the post read.
