US late-night host Stephen Colbert has accused his network of refusing to broadcast an interview with a Democratic politician over fears of retaliation by the Federal Communications Commission (FCC). CBS, the network which hosts the programme, denies that it "prohibited" the interview from being aired, saying it gave only "legal guidance". On Monday night's show, Colbert said that CBS would not show his interview with Texas lawmaker James Talarico out of concerns about a response from the FCC, which has new guidance on equal airtime for political candidates.
