The CBS stories are AP service stories. I just happened to find them at CBS.com. The Yahoo one has links to its sources as well (the Washington Post). I think most claims of bias, especially of sources like AP, Reuters and the hard reporting of the Washington Post and NY Times is an easy excuse to ignore information that doesn’t jive with that person’s world view. Everything I linked to is available from multiple sources if you don’t happen to trust the one I linked to, Google will be happy to point you to a dozen other corroborating sources.
