CNN, Fortune and Time Magazine are co-hosting a half-day economic summit in New York today.

The keynote conversation was with Treasury Secretary Timothy Geithner and moderated by Time managing editor Richard Stengel. Geither discussed his op-ed in today’s WaPo, co-written with Larry Summers.

Geithner: “What we’re trying to do is focus on the things that were at the core of our problems we saw in the first place. There are a range of other aspects of our system that you would not put in place today if you were starting from scratch. There are a bunch of things that would be nice to do if we had time and if we had capital. But we’re trying to focus on the practical issues that were at the core of those problems.”

Other speakers at today’s summit include T. Boone Pickens and Christie Todd Whitman; CNN’s Chief Business correspondent Ali Velshi, Fortune’s managing editor Andy Serwer and CNN’s Christine Romans are all on hand to moderate these discussions. You can tune in live from DC here.
