YONKERS - Westchester County Executive Rob Astorino says he is standing by fellow Republican Chris Christie, a day after the New Jersey governor apologized for an alleged political payback scheme.

Astorino, who thinking of running for New York governor this year, would need Christie's backing as he is the head of the Republican Governor's Association.

"The governor, I take him at his word. I think most people are," said Astorino. "He didn't know about it and I think he reacted the right way. He set the tone that will not be tolerated."

Christie says he had no idea two of his top aides authorized crippling highway lane closures at the George Washington Bridge that snarled traffic in Bergen County for four days back in September. On Thursday, both those aides were fired.

The lane closures that snarled traffic on the bridge were allegedly ordered as punishment for the Democratic mayor of Fort Lee, who refused to endorse Christie in his re-election bid last year.

New Jersey state lawmakers have made public 900 pages of documents that could shed more light on the George Washington Bridge closures.

The Garden State governor is also facing a federal class-action lawsuit, filed Thursday by six residents, arguing the lane closures made them late to work and caused lost wages.
