Laura Ingraham is no stranger to generating controversy. On Thursday, she made efforts to tamp down one growing around recent comments she made about a survivor of the shootings in Parkland, Florida.

Ingraham, who anchors both a popular radio program as well as the 10 p.m. slot on Fox News Channel, offered an apology Thursday for a tweet she posted making fun of David Hogg, one of the Marjory Stoneman Douglas High School students from Parkland who has led an effort to change the nation’s gun laws and end a spate of horrific shootings at various schools across the country.

“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,” Ingraham tweeted. Her earlier tweet linked to a story from TMZ and mocked Hogg for not getting into colleges.

Earlier in the day, Hogg had used social media to list advertisers on Ingraham’s Fox News program and urged his followers to prompt them to stop running commercials on her show. Several have indicated they would move advertising elsewhere. Nutrish, a pet-food company that has an association with celebrity chef Rachael Ray, said in a statement on Twitter that  it was “in the process of removing our ads from Laura Ingraham’s program. TripAdvisor, a travel company, also used Twitter to indicate that it would remove commercials from her program, “The Ingraham Angle.” Expedia, another digital travel concern. said it would do the same.

Nestle, the food giant, said via a spokesman that it had no plans to place ads in the program in the near future. Online retailer Wayfair said it took issue with Ingraham criticizing “a high school student who has lost his classmates in an unspeakable tragedy.”  Hulu, the video-streaming service, said it was “no longer advertising on Laura Ingraham’s show.” Fox News’ parent company, 21st Century Fox, is a part-owner of Hulu. That ownership stake would transfer to Walt Disney Company under the terms of a proposed $52.4 billion deal that has been struck to send a good chunk of Fox assets to Disney. Fox News would not change hands.

It was not immediately clear if the advertisers intended to pull ad dollars from Fox News Channel, or simply place their ads elsewhere on the 21st Century Fox-owned network. Last year, Madison Avenue pulled support for Bill O’Reilly’s “The O’Reilly Factor,” at the time the network’s flagship program, after revelations of settlements made to women who alleged the TV host had sexually harassed them. Fox News and O’Reilly ultimately parted ways.

Meanwhile, Ingraham invited Hogg to appear on her program. “For the record, I believe my show was the first to feature David immediately after that horrific shooting and even noted how ‘poised’ he was given the tragedy,”she said. “As always, he’s welcome to return to the show anytime for a productive discussion.” In a later tweet, Hogg said he did not accept her apology.
