The embattled anchor is set to return Wednesday to his role on 'CNN This Morning.'
According to a memo sent out to CNN employees on Monday night, Lemon will undergo "formal training" as part of his return to his role as an anchor of CNN This Morning.
"I sat down with Don and had a frank and meaningful conversation," CNN CEO Chris Licht wrote in an email, CNN reports. "He has agreed to participate in formal training, as well as continuing to listen and learn. We take this situation very seriously."
Lemon stirred controversy on Thursday when discussing South Carolina Gov. Nikki Haley's recently announced presidential candidacy and remarks she made calling for mental competency tests for presidential candidates over 75.
Lemon addressed the remarks to his co-anchors -- Poppy Harlow and Kaitlan Collins -- and quipped that Haley, 51, "isn't in her prime" herself. When pressed on the comment by his fellow anchors, Lemon doubled down, arguing, "If you Google 'when is a woman in her prime,' it’ll say 20s, 30s and 40s."
The remarks drew instant heat from critics and lead to Lemon not appearing on CNN This Morning for the first two days of the week. However, he is set to return to the show on Wednesday.
"It is important to me that CNN balances accountability with … fostering a culture in which people can own, learn and grow from their mistakes," Licht wrote in his email to CNN staffers. "To that end, Don will return to CNN This Morning on Wednesday."
Lemon first apologized publicly on Twitter on Thursday, after the episode in which he made the sexist comments, writing, "The reference I made to a woman’s 'prime' this morning was inartful and irrelevant, as colleagues and loved ones have pointed out, and I regret it. A woman’s age doesn't define her either personally or professionally. I have countless women in my life who prove that every day."
On Friday, Lemon was also given the opportunity to address CNN staffers and apologized for his comments.
"I’m sorry that I said it. And I certainly see why people found it completely misguided," Lemon said, CNN reported. "When I make a mistake, I own it. And I own this one as well."
Lemon stressed "I believe that women of any age… can do whatever they set their minds to." adding, "The people I am closest to in this organization are women... The people I seek counsel from most in this organization are women."
