- Right-wing commentator and television host Laura Ingraham mocked a school shooting survivor who has become a vocal advocate for gun control policies.
- Then the 17-year-old activist called on his more than 600,000 Twitter followers to contact Ingraham's top advertisers.
- Well over a dozen companies have since pulled their commercials from her show, "The Ingraham Angle."
Right-wing commentator Laura Ingraham has taken a week off as host of her Fox News television show after more than a dozen companies said they will pull advertisements from her program.
Among the latest corporations to cut ties with Ingraham were Liberty Mutual, which confirmed to CNBC that it doesn't plans to run anymore ads on her show, and Bayer, which made its announcement on social media.
The advertising exodus began Thursday, shortly after Ingraham sent a tweet mocking a survivor of February's mass shooting at a Parkland, Florida, high school that left 17 students and adults dead.
The student she mocked, 17-year-old David Hogg, has become a prominent figure in the debate over gun policy that has recaptured the national spotlight after the massacre.
"David Hogg Rejected By Four Colleges To Which He Applied and whines about it," Ingraham said in the tweet.
Hogg responded to the slight by calling on his burgeoning Twitter following to contact her top advertisers.
Pet food company Nutrish was the first to announce it would remove ads from Ingraham's evening news and opinion show, "The Ingraham Angle." Well over a dozen companies, including TripAdvisor, Hulu and Nestle, have followed suit since the social media controversy erupted.
Liberty Mutual told CNBC that CEO David Long addressed Ingraham's comments with employees on Friday, saying, "These comments are inconsistent with our values as a company, especially when it comes to treating others with dignity and respect."
Ingraham sent an apology to Hogg on Thursday in two tweets, after a handful of companies had already announced that they would remove their ads from her show.
Ingraham 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)
Ingraham ... 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://youtu.be/K0v7yxczipo (2/2)
Hogg did not accept the apology, saying that he would only accept it "if you denounce the way your network has treated my friends and I in this fight."
On Friday, Ingraham announced on her show that she will take a weeklong vacation for Easter.
"I'll be off next week for Easter break with my kids," Ingraham said. A Fox News spokesperson told multiple outlets that the break was already planned.
