Video of Stephen Colbert saying that the emperor and the emperor’s press corps have no clothes was stored on YouTube. When reports that C-Span had asked YouTube to pull the clip on copyright grounds, there were, among others, two reactions: (1) how can a government claim copyrights; and (2) did they do so to suppress the speech.
To answer the first – it turns out that C-Span is not a government entity. It is a not-for-profit entity established by the cable industry and certainly own and assert copyright. As for conspiracy theories, C-Span itself is distributing the clip.
