The late night television host Stephen Colbert came unglued after the first night of the Republican National Convention, launching attacks on former Fox News host Kimberly Guilfoyle and Donald Trump Jr. Colbert’s commentary definitely crossed the line.

While recapping the first night of the RNC, Colbert called Guilfoyle a “vengeful banshee” and suggested that Trump Jr. was on drugs during his speech.

“Next stop on the love train, was Trump Jr. girlfriend and the vengeful banshee who will haunt your dreams, Kimberly Guilfoyle, who screamed this message of hope,” said Colbert. “When it came to the president’s agenda, she had some very nuanced screams.”

He then played a clip of the impassioned speech that Guilfoyle gave during the convention.

“Is the loud lady gone? I’m scared,” Colbert said as he hid from the camera. “This is the first time in my life I’ve had to turn down the volume on C-SPAN. God, I’m glad we already had our kids ‘cause I think I was too close to the TV. I might have been sterilized by that.”

After social media users called out Trump Jr. for his “sweaty face” and “bloodshot eyes,” Colbert took the opportunity to imply that the president’s son had snorted cocaine before taking the stage at the RNC.

“It was his keynote address, in that he looked like he had snorted a key,” Colbert said. “So before I tell you what he said, can we zoom in on Junior’s sweaty face and wet, bloodshot eyes?”

“Either he’s high or that’s what happens when you live in the splash zone of Screamin’ Guilfoyle,” he added. “Just bring a poncho.”

Colbert will be going live every night to give his thoughts on the RNC, so you can expect below-the-belt attacks on conservatives throughout the week. Unsurprisingly, Colbert was much kinder when he gave recaps of the Democratic National Convention, treating the liberals in attendance there with kid gloves compared to how he is going after Republicans.
