From CNN, Friday morning:
Several well-placed GOP sources in Washington and Idaho have told CNN that embattled Republican Sen. Larry Craig is likely to resign soon, possibly as early as Friday.
GOP source with knowledge of the situation told CNN's Dana Bash that the Republican National Committee was poised to take the extraordinary step of calling on Craig to resign. However, that move was put on hold, the source said, because top party leaders have received indications that Craig himself is preparing to step down.
Sources have confirmed that high-level meetings on the matter were being conducted in Idaho on Thursday. Craig has been under pressure to quit since news surfaced this week that he was arrested in June at Minneapolis-St. Paul International Airport and later pleaded guilty to a disorderly conduct charge. The arrest was made by an officer investigating reports of sexual behavior in an airport restroom.
Update 5:30 p.m.: The AP says Craig will resign Saturday. Craig's staff would neither confirm nor deny the report.
