An Oct. 9 press release from campaign staffer Tom Erickson said that Sen. Norm Coleman would “hold a media availability” Friday morning. But when I arrived, Chuck Olsen of the citizen-videoblogging group The Uptake had already been refused entry. When I tried to walk in, Erickson barred me entry as well, stating that the event, held in Coleman’s campaign office was for “credentialed” media only. When I asked how one gets such credentials, he said that only “legitimate” media were welcome. As journalists from local media filed past — Star Tribune columnist Nick Coleman, MinnPost reporter Joe Kimball, TPT host Eric Eskola — Coleman staffers refused to share what criteria it used to determine what makes a news operation legit.
