What really happened with Carr is in the thread article:
"To back up for a moment:
On Monday, Late Show host Stephen Colbert told his audience that the network said that he couldn't interview Talarico on the show, citing the FCC's new guidance on equal time rules for political candidates.
"[Talarico] was supposed to be here, but we were told in no uncertain terms by our network's lawyers, who called us directly, that we could not have him on the broadcast," Colbert told the audience.
"Then I was told in some uncertain terms that not only could I not have him on, I could not mention me not having him on."CBS responded Tuesday with a statement explaining its reasoning round the equal time rule, which in turn sparked pushback from Colbert, who said that he "really don't want an adversarial relationship with the network."

"So we obeyed our network and put the interview on YouTube where it's gotten millions of views. And I can see why," Colbert said Tuesday.
"I wish we could have put it on the show where no one would have watched it ... but here's what I do want to tell the lawyers how to do their jobs.
They know damn well that every word of my script last night was approved by CBS's lawyers, who for the record approve every script that goes on the air " whether it's about equal time or this image of frogs having sex. That's a true story."
