LOS ANGELES (CBS/AP) — Just two days after being named host of the Academy Awards, Kevin Hart has stepped down following an outcry over past homophobic tweets by the comedian.

Capping a swift fallout, Hart wrote on Twitter just after 9 p.m. Thursday that he was withdrawing as Oscars host because he didn’t want to be a distraction.

Hart stepped aside just about an hour after refusing to apologize for tweets that resurfaced after he was announced as Oscars host on Tuesday. In a video on Instagram, Hart said the Academy of Motion Pictures Arts and Sciences gave him an ultimatum: apologize or “we’re going to have to move on and find another host.”

“I chose to pass on the apology,” Hart said. “The reason why I passed is because I’ve addressed this several times.”

Hart has since deleted some of the anti-gay tweets, mostly dated from 2009-2011. But they had already been screen-captured and been shared online. In 2011, he wrote in a since-deleted tweet: “Yo if my son comes home & try’s 2 play with my daughters doll house I’m going 2 break it over his head & say n my voice ‘stop that’s gay.”

In an earlier post Thursday, Hart wrote on Instagram that critics should “stop being negative” about his earlier anti-gay remarks.

“I’m almost 40 years old. If you don’t believe that people change, grow, evolve? I don’t know what to tell you,” said Hart, who added, in all-caps: “I love everybody.”

Hart’s attitudes about homosexuality were also a well-known part of his stand-up act. In the 2010 special “Seriously Funny,” he said “one of my biggest fears is my son growing up and being gay.”
