After The Guardian's Glenn Greenwald blasted MSNBC for blatant pro-Obama bias on air Thursday, the investigative reporter clarified some of his positions on his blog Friday, highlighting the “stunning irony” of a clearly biased network calling him out on “expressing opinions and having political agendas.”

Greenwald offered four clarifying points to his showdown with MSNBC, starting with highlighting the “many, many people” on the network that “constantly” defend Obama:

1) I didn't say that everyone at MSNBC constantly defends Obama. I am well aware - as Kristen Welker so notably put it - that “not everyone on MSNBC does that 24 hours a day". The indisputable point is that many, many people calling themselves journalists on MSNBC do exactly that.

But his real point is the hypocrisy and self-blindness required of MSNBC hosts to challenge him on journalistic ethics:

2) My main point was to note the stunning irony of being told on MSNBC - of all places - that a journalist "crosses the line" by expressing opinions and having political agendas. The last outlet that ought to be trumpeting that obsolete myth is MSNBC. This is, after all, a network that employs a veritable army of former Obama and DNC aides as hosts and "analysts," along with dozens of people whose entire worldview is shaped by devotion to the President and his party's interests.

I'm not someone who believes that it's wrong for journalists to have opinions and agendas, but whatever else is true, a network that does this and this and this isn't exactly in a very good position to lecture journalists on the need to be opinion-free and without political agendas.

His third argument is that a journalist defending his source is far from “crossing the line,” as he was accused of Thursday, but rather something that is “smack in the middle” of a journalist’s job description. Greenwald also finds it particularly ironic that a network that journalists like those on MSNBC seemed to find it “perfectly proper... to devote their entire careers defending and venerating the most powerful official in the nation.”

Greenwald ends the post with his fourth and final point:

4) If you want to argue with someone who (unlike me) actually made absolutist claims about MSNBC's blinding pro-Obama hackery, go find these two individuals:

Bill Clinton

Barack Obama
