From NPR News, this is ALL THINGS CONSIDERED. I'm Audie Cornish. The stage is set in Denver for the first presidential debate tonight at 9:00 p.m. Eastern. The candidates are suiting up, reporters are gathering, live tweeters are sharpening their virtual pencils. And NPR's Mara Liasson is in Denver and she joins us for a preview. Welcome, Mara.
MARA LIASSON, BYLINE: Hi, Audie.
CORNISH: So what is the format for tonight's debate?
Fox News and other conservative media outlets claimed to have a scoop on Tuesday they called "Obama's other race speech." The tape that was supposed to turn this election around, however, was documented and reported on in 2007 by the very same news outlets.
After a two-year investigation, a Senate report released Wednesday criticizes the Department of Homeland Security's "fusion centers" as ineffective, expensive, and encroaching on civil liberties. The centers were created after Sept. 11 to improve communication between federal counter-terrorism agents and state and local law enforcement. A department spokesman called the report flawed.
