Not taking money from the people you’re covering is the barest minimum of journalistic ethics. Regardless, of whether you or I agree with anything else on that site, Adam Davidson, or whoever else, failing to meet that basic standard should be patently disqualifying. The fact that he was the host of a flagship, economic reporting show, even more so.
There are many other reasons I find it hard to take NPR’s claims of impartiality seriously, but this one is so glaringly wrong that it speaks for itself.
