That’s the rumor according to Newsbusters by way of Booker Rising:

I took the shuttle bus back to Minneapolis, and I overheard a convention organizer named Phil telling a convention delegate that the protesters on Wednesday night got through because of media credentials that were traced back to MSNBC (he told her that each credential has an individual bar code for each convention invitee). They suspect MSNBC this time as well.

Sounds plausible, and if true MSNBC should be punished by being denied access to any Republican candidate and/or event anywhere.

And I’m not saying that out of a desire to see MSNBC be less slanted to the left.

As far as I’m concerned, MSNBC can be as biased as they want to be.  They can use Obama-disciples Chris Matthews and Keith Olbermann to cover every political event if they want to.  They can spend all their on-air time talking about what doodie heads McCain or Palin or any other Republican is.  That’s fine.  It’s their news network, and they can do what they want.

But actively assisting a far-left organization in disrupting a political event is over the line.
