If Christie runs for president in 2016, a Republican committeeman from New Hampshire, told CNN's Dan Merica it won't "make any difference whatsoever."

“People in New Hampshire could care less about whether some bureaucrat working on his staff did something stupid like this," Stephen Duprey said.

“By way of comparison, one seems to care of that Secretary of State Clinton was negligent and that ended up in the death of four Americans in Benghazi. They sure aren't going to care about a traffic lane closure in New Jersey.”

“I also think New Hampshire voters will like the way he dealt with The mess by taking responsibility and making changes. It demonstrates a nice contrast to the current administration.”

“So my bottom line take on this is that it is much ado about nothing and the New Hampshire primary voters could care less.”

"If you lie when I ask you a question, you're fired. That's it," Christie says.

"It is a rare moment when I raise my voice in this office," he says, adding the last time he did was four weeks ago when he was pressing his staff members about the issue, asking whether they knew anything.

Christie says he could count on his hand the number of times he had a conversation with David Wildstein, his appointee at the Port Authority who was involved with the bridge scandal. Wildstein resigned last month. Who is David Wildstein?

Asked if any level of political retribution is acceptable, Christie says no. "Political fighting? Sure," he adds.

Christie says if the mayor of Fort Lee won't see him, he'll go see others who live in Fort Lee.

Christie says he didn't call the mayor before the press conference, but he was planning to call him afterwards to see if he wanted to meet with him.

CNN Chief Political Analyst Gloria Borger said she thinks Christie "did well" in the press conference, but said the question we did not get an answer to was: Why did Bridget Kelly decide that this was a smart thing to do?

Republican Rep. Michael Grimm, R-New York, released a statement saying “Governor Christie demonstrated true leadership and accountability during today’s press conference."

“I have known Governor Christie since he was a United States Attorney with a distinguished anti-corruption record and I was an undercover agent working a high profile public corruption case with his office. I know him to be a man of unquestionable honor and ironclad integrity, and I take him at his word," he added.

CNN Crossfire co-host S.E. Cupp, a Republican, thought Christie was "very believable" today. He was "humble" and "contrite," not his usual demeanor.

Democratic Rep. Frank Pallone, Jr. of New Jersey released a statement saying "Today’s press conference served to raise more questions than it answered. All of the facts surrounding this incident must be put on the table immediately and any and all appropriate actions should be taken to hold everyone involved accountable."
