ABC News' David Kerley reports: A spokesman for embattled Idaho Republican Senator Larry Craig has said he will neither confirm nor deny reports by the Associated Press that Craig will announce his decision to resign Saturday morning.
Aides will only say the Senator will announce his "future plans" Saturday morning.
Pressure has been mounting on Craig to resign after news broke of his arrest in an undercover sting operation in an airport men's room. Craig pleaded guilty to disorderly conduct on Aug. 1 but has maintained that he did nothing wrong.
Republican leaders have launched investigations into the matter and Republican senators have publicly called on Craig to step down.
