It seems Markos Moulitsas, founder of the Daily Kos, has been banned from MSNBC for tweets he made about Joe Scarborough. Here’s the post from Markos describing the entire event with the letter from MSNBC’s Phil Grffin to Markos confirming the move:

Markos,
Blog if you must, but here is my on the record statement to you which I ask that you print in full:
Yes, after I became aware of the ugly cheap shot you took at Joe on Twitter, I asked the teams to take a break from booking you on our shows for a while. I found the comments to be in poor taste, and utterly uncalled for in a civil discourse.
I’m hoping this will be only temporary and that the situation can be resolved in a mature fashion, but until then I just don’t know how one could reasonably expect to be welcomed onto our network while publicly antagonizing one of our hosts at the same time.
The DailyKos community has been among the most supportive of MSNBC, and we continue to appreciate that support.

More to come I’m sure.
