At 9:00 EST on CNN.
Update: Apparently she was bumped by Thomas Friedman. He was very good, however. But I missed "The Stagers" (looked like a repeat anyway).
I'd received this email earlier:
Just wanted to let you all know that Steph has just been booked on CNN's "Larry King Live" tonight at 9pm Eastern / 6pm Pacific. Be sure to tune in to see what she has to say this time!
