Parkland, Fla., shooting survivor David Hogg doubled down on his criticism of Fox News host Laura Ingraham as advertisers continue to flee her show over a comment she made against Hogg.

In the past few days, more than a dozen companies have pulled their advertisements from “The Ingraham Angle” in response to her tweet mocking Hogg for being rejected from colleges.

“A bully is a bully and it’s important that you stand up to them,” Hogg said on CNN Saturday.

Hogg, one of the leaders of the “March for Our Lives” movement and an outspoken gun control activist following the shooting at his high school, also called out Ingraham for her comments earlier this year about NBA stars LeBron James and Dwyane Wade.

Ingraham sparked major outcry after she said that James and Wade should “shut up and dribble” rather than comment on politics. {mosads}

“She’s tried calling out people at Dartmouth University for their sexual orientation and she told Lebron James to shut up and dribble,” Hogg said on CNN. “I don’t see any apology for those people.”

Hogg responded to Ingraham’s original comments by tweeting a list of her advertisers and urging his followers to contact them.

Ingraham apologized after companies began pulling their ads, but Hogg refused to accept the apology.

Any student should be proud of a 4.2 GPA —incl. @DavidHogg111. On reflection, in the spirit of Holy Week, I apologize for any upset or hurt my tweet caused him or any of the brave victims of Parkland. For the record, I believe my show was the first to feature David…(1/2)

… immediately after that horrific shooting and even noted how “poised” he was given the tragedy. As always, he’s welcome to return to the show anytime for a productive discussion. WATCH: https://t.co/5wcd00wWpd (2/2)

I 100% agree an apology in an effort just to save your advertisers is not enough. I will only accept your apology only if you denounce the way your network has treated my friends and I️ in this fight. It’s time to love thy neighbor, not mudsling at children. https://t.co/H0yWs4zMGk

Hogg said on CNN that it’s “disturbing” that Ingraham has not been held accountable for her past comments.

“It’s really sad, it’s disturbing to know that somebody can bully so many people and just get away with it, especially to the level that she did,” he said. “I think now with advertisers standing with us, we can accomplish anything.”

Ingraham announced Saturday that she is taking a preplanned break from her show next week.
