Idaho Sen. Larry Craig plans to announce his future plans Saturday following calls from Republicans urging him to resign after an arrest in connection to a police sex sting. Dan Whiting, Craig's spokesman, said there would be an announcement Saturday but would not say whether Craig will step down. Idaho Gov. C.L. "Butch" Otter already appears to have settled on a successor: Lt. Gov. Jim Risch, according to several Republicans familiar with internal deliberations.
