"Progress is slow, but I'm in it for the long haul," Will says after expressing a string of less-than-popular political views.

Sorkin, who won an Academy Award for penning the screenplay forThe Social Network, will executive produce and write after spending time with high-profile cable news personalities like Olbermann and Chris Matthews to understand the world he planned to re-create.

Scott Rudin (The Social Network) and Alan Poul (Six Feet Under, The Big C) serve as executive producers, withGreg Mottola directing the pilot.

Newsroom becomes the latest in Sorkin's behind-the-scenes TV takes, following his exploration of a sports talk show in SportsNight and focus on sketch comedy in Studio 60 on the Sunset Strip.
