Sen. Larry Craig has some 'splainin to do:

Craig was arrested at the airport on June 11, according to Roll Call, a Capitol Hill newspaper. According to police reports, Craig kept watching the undercover police officer through a crack in the bathroom stall, Roll Call reported. Craig then entered the next-door stall and placed his luggage against the opening under the stall door.

"My experience has shown that individuals engaging in lewd conduct use their bags to block the view from the front of their stall," said the officer, Sgt. Dave Karsnia.

The report continued: "At 1216 hours, Craig tapped his right foot. I recognized this as a signal used by persons wishing to engage in lewd conduct. Craig tapped his toes several times and moves his foot closer to my foot. ... The presence of others did not seem to deter Craig as he moved his right foot so that it touched the side of my left foot which was within my stall area."

The report said that Craig swiped his hand beneath the stall divider several times and that Karsnia showed his police identification under the stall.

Roll Call reported that Craig was detained about 45 minutes and questioned by officers at the Airport Police Operations Center. At one point, police reports said, Craig handed the arresting officer a business card that identified him as a U.S. senator and said, "What do you think about that?"

I bet Craig is asking himself that today.

CNN is reporting that "influential" Republicans in Idaho are saying that Craig should resign.

Thus, the Larry Craig senate career death watch begins.
