"I'm delighted and honored that so many of my friends -- who are not coincidentally among the top progressive and entertainment voices in the country today -- will be joining me as contributors to Countdown on Current," Olbermann said in a statement. "I hope these talented individuals, and the others we are to announce in these weeks before the premiere on June 20 will give viewers a sense of the strength and depth of the franchise we're assembling."
