It’s not like we didn’t know that Ezra Klein wasn’t a political hack posing as a journalist. Now we know for sure.

“From JournoList to activist, it appears that WaPo‘s liberal blogger Ezra Klein is once again blurring the lines between being a journalist and trying to sway politics. In what appears to be at a minimum a breach of journalism ethics, Klein spoke to a group of Senate Democratic Chiefs of Staff last Friday about the Supercommittee, just days before the Committee announced its failing. “It was kind of weird,” said a longtime Senate Democratic aide, explaining that while people “enjoyed it” and gave it “positive reviews” this sort of thing is far from typical.

A longtime Washington editor who deals with Capitol Hill regularly also said this is not the norm: “”I have never heard of a reporter briefing staffers. It’s supposed to be the other way around. This arrangement seems highly unusual.”

The Washington Post will have no choice at this point than to fire Klein. This is definitely a violation of journalist ethics, unless the Post truly believes that doesn’t matter.
