TRENTON - (AP) - Gov. Chris Christie has put forth a former state attorney general to be the next chairman of the embattled Port Authority of New York and New Jersey.

Christie announced on Tuesday that he's recommended John Degnan to replace David Samson, who resigned last month.

The registered Democrat served as attorney general from 1978 to 1981.

Christie says he wanted someone with "unquestioned credentials."

The Port Authority has been hit by several resignations since details emerged about a lane-closing scandal at the George Washington Bridge last fall.

His nomination requires state Senate confirmation.
