Más fuentes confirman que Christie dirá que NO

ABC News:

New Jersey Gov. Chris Christie will not run for president, according to a source with direct knowledge of the governor’s thinking.

POLITICO.com:

With the caveat that his team has said nothing and the governor himself has yet to speak - and could say something different - sources tell POLITICO Gov. Chris Christie isn't launching a presidential campaign.

Two sources said he has started letting people know in advance of his press conference, with a truncated window.

"He is not running," said a fundraiser informed of the decision. "Mary Pat the gov just called tier one [donor] group to say he was out."
