He'd apologized, but "upon further reflection," he resigns from MSNBC.
ADDED: I think this is all such nonsense (including the ousting of Alec Baldwin). They can't trust people to understand explanations. Bashir — if he was ever worth having his own show — should be able to say very clearly that he intended to express the depth of the horror of slavery and therefore why it should never be used as a metaphor. Now, of course, he'd be open to the criticism that he only chose to go where he did because his target was Sarah Palin, but he could confess to that, say that was wrong, and dedicate himself to permanent across-the-board opposition to slavery as a metaphor.
