FishbowlDC's Patrick Gavin answers some of the questions asked on this blog earlier today:
FishbowlDC hears that MSNBC General Manager Dan Abrams asked David Shuster to apologize for [the] Rep. Marsha Blackburn incident and even wrote the bulk of Shuster's on-air apology.
We also hear that an on-air explanation of this episode is not expected today, with MSNBC hoping to pretend the entire episode never happened.
>More, from an MSNBC insider: "Shuster strenuously objected to Dan in a heated argument overheard by multiple MSNBC staffers. Shuster asked Dan for more time to check out Blackburn's assertions. Dan refused and wanted to end the controversy."
