MSNBC says it will now tell viewers that Richard Wolffe -- who is a regular commentator on the network, and last week guest-hosted Countdown -- works for a corporate P.R. firm.

Network spokesman Jeremy Gaines told TPMmuckraker in an email:

We should have disclosed Richard's connection to Public Strategies. We will do so in the future.

Over the weekend, Salon's Glenn Greenwald expressed outrage about the arrangement, and the lack of disclosure. We picked up the story this morning, and told you a bit about P.S.I.'s corporate work.
