TRENTON, N.J. - New Jersey Gov. Chris Christie gave a wide ranging State of the State address Tuesday, but started his remarks by addressing the scandal that has rocked his office over the last week. The Republican governor acknowledged that "Bridgegate" has "certainly tested" his administration.

"We let down the people we are entrusted to serve," Christie said in a speech aimed at the two houses of the state legislature as well as his constituents in the Garden State. "I know our citizens deserve better. Much better. I am the governor and I am ultimately responsible for all that happens on my watch - both good and bad."

It was a different moment - and a different mood - than just a few days ago. On Tuesday, Christie was greeted by extended applause from elected officials and guests and promised to "cooperate with all appropriate inquiries to ensure this breach of trust does not happen again." Last week, he was greeted by a mostly silent press corps. On Tuesday, at the formal event at the State Capitol, he answered no questions. Last week he took dozens of them.
