Former MSNBC host and soon-to-be Current TV host Keith Olbermann announced a slew of new contributors to his program today.

They include Rolling Stone journalist Matt Taibbi, former Richard Nixon staffer John Dean, journalist Jeremy Scahill, actor Donald Sutherland and even astronomer Derrick Pitts, who Olbermann stressed will not be on to talk about politics, but other news of the day.

“Obviously we are going to have Derrick talk about the moon, rather than the days politics,” Olbermann said in a call this morning.

The announcement came just a day after Olbermann returned to his old stomping ground at 30 Rock to appear on “Late Night with Jimmy Fallon.” Among other subjects, Olbermann talked about Rachel Maddow, who he says he hopes will be joining him at Current TV eventually:

On the most recent episode of “Real Time with Bill Maher,” NBC’s Chuck Todd joined Rep. Jan Schakowsky and Jay Leno on the panel for the week’s discussion. Journalist Jeremy Scahill also appeared to discuss Blackwater and ended up singling out Todd, accusing: “Chuck, you called it political cat-nip to talk about the CIA and Cheney’s role in this, because it distracts from the important issues. This is a central issue and you called it cable cat-nip.”

In an email to Salon.com’s Glenn Greenwald, Scahill said the following of his appearance on the show and his on-air disagreement with Todd:

Right as we walked off stage, he said to me “that was a cheap shot.” I said “what are you talking about?” and he said “you know it.” I then said that I monitor msm coverage very closely and asked him what was not true that I said on the show. He then replied: “that’s not the point. You sullied my reputation on TV.”
