"As several bloggers have rightly noted, I erred yesterday on MSNBC when discussing Karen Tumulty's piece about the Obama campaign's efforts to combat rumors and smears. I said the rumor about Michelle Obama making a derogatory comment about whites was started by conservative bloggers. That was a mistake.

Johnson said he heard it from someone in touch with "a senior Republican", whatever that means. Its actual origins are unknown.
