After a day of Saturday specials on the cablers, the networks are gearing up for the Asian markets opening later today and the opening of Wall Street tomorrow following Friday’s S&P downgrade of the U.S. CNN’s special coverage continues tonight with a 9pmET special hosted by Christine Romans. Fox Business will produce a 2-hour special tonight at 9pmET hosted by Gerri Willis. Also, at 8pmET Bloomberg Television presents a two-hour live report anchored by Tom Keene and Adam Johnson.

CNBC’s also got a special on at 8pmET called “Markets in Turmoil.” As part of it, CNBC’s Chief Washington Correspondent John Harwood will speak with Treasury Secretary Timothy Geithner who announced today he’s staying with the Obama Administration through the election.

This morning on “Meet the Press” former Fed Chairman Alan Greenspan said, “What I think the S&P thing did was to hit a nerve that there’s something basically bad going on and it’s hit the self esteem of the United States. The psyche. And it’s having a much profounder effect than I conceived could happen, because the economics of what they’re talking about is very clear.”
