For lying about his role in covering the election for the network, NOT because he's a serial liar and trouble-maker in general. Here's the letter they sent him:
We have spent the past several days trying to make clear to you your limited role as a participant in our digital town hall to be streamed on ABCNews.com and Facebook. The post on your blog last Friday created a widespread impression that you would be analyzing the election on ABC News. We made it as clear as possible as quickly as possible that you had been invited along with numerous others to participate in our digital town hall. Instead of clarifying your role, you posted a blog on Sunday evening in which you continued to claim a bigger role in our coverage. As we are still unable to agree on your role, we feel it best for you not to participate.Shit. Why the fuck did they even think it was a good idea to invite him to do anything in the first place???
