Donald Trump Jr. hit back Thursday after a “TV writer” threatened to come after his daughter Chloe over the temporary separations of families on the Mexico border.

“This is what the other side is all about. The more I am exposed to them the more obvious it becomes. Hate and bullshit is their political platform,” Trump Jr. captioned his post on Instagram, along with a screenshot of the threat against his daughter, which read, “Don’t worry, we’re coming for Chloe, too.”

“It’s literally all they have,” he added. “We sure as hell know it’s not jobs, freedom or the economy. They can say or do anything and nothing ever happens, a standard conservatives don’t have the luxury of.”

“Not only do you have a celebrity attacking a 12-year-old boy wishing him to be in a cage with pedophiles but another ‘TV writer’ threatening my 4-year-old when I hit back and challenge one of their Hollywood groupthink cult leaders. It only strengthens my resolve. #enoughisenough #maga.”

The comments came after Trump responded to actor Peter Fonda who tweeted that, “We should rip Barron Trump from his mother’s arms and put him in a cage with pedophiles and see if [Melania Trump] will stand up against the giant asshole she is married to.”

You’re clearly a sick individual and everyone is an internet badass but rather than attack an 11 year old like a bully and a coward why don’t you pick on someone a bit bigger. LMK. https://t.co/8OhiQ0aZmO — Donald Trump Jr. (@DonaldJTrumpJr) June 20, 2018

Fonda’s tweet has since been deleted and he apologized for the “inappropriate and vulgar” comment via his manager in a statement to The Daily Caller.

“I tweeted something highly inappropriate and vulgar about the president and his family in response to the devastating images I was seeing on television. Like many Americans, I am very impassioned and distraught over the situation with children separated from their families at the border, but I went way too far. It was wrong and I should not have done it. I immediately regretted it and sincerely apologize to the family for what I said and any hurt my words have caused,” Fonda explained.
