Late Show host Stephen Colbert was horrified by President Donald Trump’s speech at the Turning Point USA Teen Student Action Summit on Tuesday, describing it as “disturbing” and a “really bad speech.”

As the keynote speaker at the Turning Point USA Teen Student Action Summit, Trump delivered an 80-minute speech to conservative students that covered everything from political correctness to his recent controversies with four far-left Democratic Congresswoman known as “The Squad.”

“Today, Donald Trump strapped on a millstone and some scuba gear, and gave a really bad speech to conservative kids at something called Turning Point USA’s Teen Student Action Summit,” said Stephen Colbert as he began his monologue.  “Teen student action is usually something the vice principal has to break up underneath the bleachers.”

Colbert then played a clip of attendees cheering as a Donald Trump highlight reel was played before he took the stage, which included him mocking Rosie O’Donnell and his “because you’d be in jail” rebuttal to Hillary Clinton during the 2016 presidential debates.

“That bloodthirsty cheering gives a chilling new edge to the phrase ‘I believe the children are our future,’” Colbert commented.

The 55-year-old funnyman also attacked Trump over his mocking of Rep. Rashida Tlaib (D-MI), who he described as “vicious” and “like a crazed lunatic” amid widespread booing from the audience at the mention of her name.

“Wow, that’s even more disturbing with those high, youthful voices,” Colbert quipped. “Send her back! Buy me beer! Let me vape!”
