Hello JDAM,
PBS did not slant it at all. There was no report of the event on PBS. Apparently they didn't even consider it newsworthy.
I gather from that that it wasn't really a town hall at all. It was a selected audience question and answer session hosted by a commercial news network. President Biden probably agreed to it because he felt that they would not be overly aggressive, and it would be a way to straight-talk to the public and make his first network appearance.The network did it to sell advertising and the president did it to get exposure in a different way than his predecessor who is now seen in an unfavorable way.
I gave you the link on cnn to watch it. have you yet?
