HBO host Bill Maher ripped CNN host Kaitlan Collins during his show this week over the network’s left-wing bias, which he said is on constant display.

Maher made the remarks Friday night on “Real Time” while discussing an interview that Collins had with Stephen Colbert on CBS where she and her network were laughed at when Colbert said that they were a straight news organization.

“You made press because you were on Stephen Colbert’s show, and he said something like, ‘You guys at CNN just report the news straight.’ And the crowd burst into laughter,” Maher said. “I’m a big rooter for CNN, but that tells you a lot, doesn’t it?”

Maher asked Collins how she thinks her network is doing in this “terribly divided country” where both sides “just hate the other side.”
