PBS' Bill Moyers, host of "Now" and avowed liberal, got some media scrutiny last year when The Weekly Standard's Stephen F. Hayes pointed out, among other things, that there was a pattern of Moyers financing organizations' research and then interviewing them on his show -- all without disclosing the relationship.

Despite a promise to fully disclose such relationships (which wasn't any big deal anyway -- in Moyers' view), Hayes has caught him at it again.

Expect another round of mudslinging as Moyers attempts to defend behavior that he would find scandalous if done by anyone other than himself.
