The latest report has Republican officials confirming that Senator Larry Craig will resign his seat tomorrow effective later on in September. Borrowing from a PB commenter, it appears the “other shoe” has dropped in the case. Craig’s bizarre denial wasn’t enough to withstand pressure from angry GOPers.

Bowing to intense pressure from his Republican colleagues, Sen. Larry Craig (R-Idaho) will announce Saturday that he is resigning his seat in Congress following revelations that he was arrested in a men’s bathroom and pleaded guilty to disorderly conduct after an encounter with an undercover police officer.

Republican sources said Craig, 62, a social conservative who has steadfastly opposed gay rights, will announce his resignation in Boise, Idaho, at 10:30 a.m. MDT just days after defiantly announcing “I am not gay. I never have been gay.”

Idaho Gov. C.L. “Butch” Otter, a Republican, plans to appoint Lt. Gov. Jim Risch to fill the last 16 months of Craig’s term in the Senate, according to a GOP source. Craig is expected to officially leave the Senate on Sept. 30, sources said.
