Michael Flynn Jr., the son of former national security adviser Michael Flynn lambasted Parkland student David Hogg on Sunday, saying he hadn’t been smacked enough growing up.

“Someone (hint: parents) clearly didn’t smack this kid much growing up. Your emotional high will run out soon so savor it while it lasts,” Flynn Jr. tweeted in reference to Hogg.

His tweet came in response to Hogg rejecting an apology for a critical tweet Fox News host Laura Ingraham posted about his college prospects. Hogg has become a vocal advocate for gun control since the deadly shooting at his high school in Parkland, Fla.

Ingraham last week posted a tweet critical of Hogg and shared a Daily Wire story saying that Hogg was rejected from four colleges he had applied to.
Hogg responded, asking who Ingraham’s biggest advertisers were. He then tweeted out a list of her advertisers and called for people to contact those companies.

Multiple companies that advertised during Ingraham’s Fox News program have since announced they would pull their ads.

Ingraham later apologized, saying she was sorry for “any upset or hurt my tweet caused him or any of the brave victims of Parkland.”

Hogg rejected her apology last week, saying he would only accept it if she denounced the way her network has “treated my friends and I in this fight.”

Flynn Jr. and his father have been investigated as part of the special counsel’s probe into Russian interference in the 2016 election, a fact that MSNBC’s Joy reid pointed out on her response to Flynn Jr.’s tweet:
