The news came after at least 11 advertisers announced they would no longer advertise on Ingraham's show following backlash over a tweet she posted mocking Hogg's college rejections.
"David Hogg Rejected By Four Colleges To Which He Applied and whines about it," she wrote, adding that he was "dinged by UCLA with a 4.1 GPA ... totally predictable given acceptance rates."
Hogg responded by asking Ingraham who her biggest advertisers are and organized a boycott. Wayfair, Nestle, Hulu, TripAdvisor and other companies soon pulled their ads from the show.
Ingraham issued an apology Thursday, saying she was sorry "for any upset or hurt my tweet caused [Hogg] or any of the brave victims of Parkland."
Hogg replied that he would accept Ingraham's apology "only if you denounce the way your network has treated my friends and I in this fight," adding, "It's time to love thy neighbor, not mudsling at children."
