UPI is reporting that the FBI has "hard evidence" on two of Cheney's staffers in the Plame probe, John Hannah and Lewis "Scooter" Libby. They appear to be leaning on Hannah, suggesting he faces jail time, to get him to implicate higher ups, a tried and true tactic of federal prosecuters. This dovetails nicely with George Tenet's speech in which he defended the CIA and said that they never concluded to the President that Iraq was an immminent threat.
Looks like the roost is getting crowded with all those homing chickens.
