As far as I know, “Tehran Bureau” is an independent organization. A couple of years ago, they had their own url (tehranbureau.com?) but didn’t have funding to keep it going. That’s when they relocated to be a part of pbs.org.
Here’s the take at Russia Today on Youtube.

Thank you. I am surprised by the honesty of that comment being in any way associated with PBS.
