"It was a mistake," Harrison said. "I made a mistake. I am an imperfect man. I made a mistake and I own that. I believe that mistake doesn't reflect who I am or what I stand for. I am committed to the progress, not just for myself, also for the franchise."
Harrison made headlines last month after comments he made during an interview with former Bachelorette Rachel Lindsay. In the Feb. 9 interview, Harrison defended Kirkconnell's past racist actions, and encouraged people to offer her "grace."
Looking at his interview with Lindsay now, Harrison said he's "saddened and shocked at how insensitive I was."
"I didn't speak from my heart and that is to say I stand against all forms of racism. I am deeply sorry," he said. "I'm sorry to Rachel Lindsay and I'm sorry to the Black community."
Harrison noted that he has spoken to and apologized to Lindsay since the interview, though he has not done so again since she deactivated her Instagram account due to harassment she received.
"I talked to Rachel, not since she deactivated her Instagram account, but talked to her initially and apologized and I want to do so again," he said. "I am incredibly sorry. To anyone who is throwing hate towards Rachel Lindsay, please stop. It is unacceptable."
Much of the hate Lindsay has been subjected to has been from people who think that Harrison is being treated unfairly. Harrison, though, said he's "not a victim here."
"I made a mistake and I own that," he said. "Racism, oppression, these are big dynamic problems and they take serious work and I am committed to that work."
Part of that work is coming with the help of Dr. Michael Eric Dyson, who's a race educator and strategist, as well as a faith leader.
"Dr. Dyson often talks to me about counsel, not cancel. That is full accountability, understanding what you didn't understand," he said. "Owning that, learning from that, seeking counsel often in the community that you hurt, learning from them, listening, gaining experience, knowledge, and moving forward."
Harrison also touched on his decision to step aside from the franchise for a period of time, and expressed his want to return eventually.
"I plan to be back and I want to be back," he said. "This interview is not the finish line. There is much more work to be done and I am excited to be a part of that change."
A source tells ET that, while Harrison hoped for the interview to be done in person, that wasn't possible due to the ongoing pandemic.
"Chris wanted to fly and do the interview in person in New York for an even more personal conversation, but GMA hasn’t been doing in-person interviews because of COVID," the source says.

Harrison originally issued his own statement, apologizing for "wrongly speaking in a manner that perpetuates racism. In a second apology issued on Feb. 13, he announced that he'd be taking time off and would not be hosting the After the Final Rose special with James and his final pick.

A source told ET that 30-year-old Acho is ready for his hosting duties. "He feels confident about replacing Chris Harrison for the episode and believes he can lead important conversations that viewers should learn about and be part of," the source said.
