Idaho ? Sen. Larry Craig is reconsidering his decision to resign after his arrest in a Minnesota airport sex sting and may still fight for his Senate seat, his spokesman said Tuesday evening.

“It’s not such a foregone conclusion anymore, that the only thing he could do was resign,” Sidney Smith, Craig’s spokesman in Idaho’s capital, told The Associated Press.

“We’re still preparing as if Senator Craig will resign Sept. 30, but the outcome of the legal case in Minnesota and the ethics investigation will have an impact on whether we’re able to stay in the fight – and stay in the Senate,” Smith said.

Craig, a Republican who has represented Idaho in Congress for 27 years, announced Saturday that he intends to resign from the Senate on Sept. 30. But since then, he’s hired a prominent lawyer to investigate the possibility of reversing his plea, his spokesman said.

Craig was a no-show Tuesday as Congress reconvened after a summer break and it wasn’t clear whether he’ll return at all since deciding to resign over his guilty plea in a sex sting this summer at the Minneapolis-St. Paul International Airport.
