I first saw this story at HotAir. A quote from Big Gogernment sums it up:
"Let’s start with the AP’s clear surrender of any kind of impartiality when reporting about Breitbart and the Tea Party movement. Political writer Michael R. Blood, who filed this report, needs to be taken off the Tea Party beat immediately. If he can’t report a simple, straightforward fact like Breitbart disputing the accounts of racial epithets without the nonsensical caveat of “although he didn’t provide any evidence,” then how can he be trusted to fairly report on other activities from the increasingly influential political movement he is covering?
"It seems to me, that perhaps Mr. Blood needs to provide evidence that he’s not biased. How’s that, Mr. Blood?"
