Trump Jr. ripped for 'liking' conspiracy theories on Parkland survivors Trump Jr. 'liked' Twitter posts that contained conspiracies about the shooting.

 -- Comedians on the late-night TV circuit got serious on Wednesday as they slammed Donald Trump Jr. for reportedly boosting conspiracy theories about last week's school shooting in Florida, including one that called a survivor an agent of “the deep state media.”

The saga started after the president’s eldest son “liked” two Twitter posts that defamed David Hogg, a senior at Marjory Stoneman Douglas High School in Parkland, Florida, where a former student allegedly shot and killed 17 students and teachers last week.

One of the posts he “liked” contained an image of Hogg -- whose father is a former FBI agent -- and a link to a video with the following caption: “Outspoken Trump-hating school shooting survivor is son of FBI Agent: MSM [mainstream media] helps prop up incompetent bureau.”

Jimmy Kimmel, host of “Live,” was one of the many late-night hosts who bashed Trump Jr. for endorsing the post.

“People like Donald Trump Jr., the president's least-favorite son, are perpetuating this kind of stuff,” Kimmel said in his opening monologue Tuesday. “These are impressive kids who should be applauded.

“But some are attacking them. People who call them fake news, who call them fake students, they say they are crisis actors -- the actors who orchestrate tragic events in order to advance some kind of liberal agenda,” he added.

“The Late Show” host Stephen Colbert was even harsher in his criticism of Trump Jr.

“And it wasn't just internet crazies attacking these kids online. They were joined by Trump's son -- and man telling the bouncer to check the list again -- Donald Trump Jr., who ‘liked’ tweets attacking a Florida massacre survivor,” Colbert said. “Well, you know what they say: The d--che doesn't fall far from the bag.”

The late-night comments came just a day after an aide to a Florida state lawmaker was fired for allegedly referred to Hogg and other Stoneman Douglas students as “actors that travel to various crisis when they happen.”

Hogg, who's rallied for tougher gun laws in the aftermath of the Feb. 14 shooting, rejected the "disturbing" claims in an interview with CNN on Wednesday.

“I’m not a crisis actor, I’m someone who had to witness this and live through this and I continue to be having to do that,” he said in the interview. “The fact that these people refuse to believe that something like this could happen is something that all of us don’t want to believe, but the sad truth is that it is.

“I’m the son of a former FBI agent and that is true, but as such it is also true that I go to Stoneman Douglas High School, I was a witness to this,” he added.
