Trump announced shortly before her husband's election she would make cyberbullying a key issue for her office as first lady.

The comments from Lauren Hogg come after Ingraham tweeted a Daily Wire story Wednesday about David Hogg getting rejected from four colleges.

“David Hogg Rejected By Four Colleges To Which He Applied and whines about it. (Dinged by UCLA with a 4.1 GPA...totally predictable given acceptance rates,)” Ingraham tweeted.

David Hogg — who has become a vocal advocate for gun control — replied a few hours later, tweeting at the Fox News host and asking who her biggest advertisers were.

He later tweeted out a list of Ingraham's advertisers, telling people to contact those companies.

Ingraham later apologized in a pair of tweets on Thursday:

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) — Laura Ingraham (@IngrahamAngle) March 29, 2018

... 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) — Laura Ingraham (@IngrahamAngle) March 29, 2018

Hogg has emerged as a national figure in the weeks since a gunman opened fire at Marjory Stoneman Douglas High School in Parkland, Fla., killing 17 people.

He helped to organize and lead the March for Our Lives rally Saturday in Washington, D.C., and has been warning lawmakers that they will be voted out of office if they don't pass new gun laws.

He has also faced criticism and has been at the center of conspiracy theories since he began speaking out for gun control.
