"Tracy Morgan should apologize immediately," the Arc CEO Peter Berns, told E! News. "This quote is far too offensive to be excused as comedy, and it is very hurtful to people with intellectual and developmental disabilities and their families. "Mr. Morgan has an incredibly powerful platform from which to fix this, and if he's learned anything in the last few weeks, he can't bomb this apology."

There were reportedly no audience walkouts at the New York event as there had been at the Nashville show, where Morgan said he would "pull out a knife and stab" his own son if he were gay.

Those comments gained attention after audience member Kevin Rogers posted them on his Facebook page.

According to Rogers, Morgan "said if his son that was gay he better come home and talk to him like a man and not [he mimicked a gay, high pitched voice] or he would pull out a knife and stab that little N (one word I refuse to use) to death. ... Tracy then said he didn't [expletive] care if he [angered] some gays."

Morgan's tirade was full of homophobic references and expletives, according to Rogers' Facebook account.

Afterward, several in Hollywood spoke out against the actor-comedian, including Wanda Sykes, Chris Rock, NBC entertainment chief Robert Greenblatt and Morgan's 30 Rock co-stars Tina Fey, Alec Baldwin and Cheyenne Jackson.

Meanwhile, Marlon Wayans defended Morgan, who has since apologized: "I know how bad bullying can hurt. I was bullied when I was a kid. I'm sorry for what I said."
