(CNN) - New Jersey Gov. Chris Christie, who was rumored to be a potential V.P. pick for Mitt Romney, gave new details Monday on the moment he learned his name would not appear on the ballot as Romney's running mate.
At a press conference in Asbury Park, New Jersey, Christie said Romney e-mailed him on Aug. 10, the night before the presumptive GOP nominee announced Rep. Paul Ryan as his pick.

In the e-mail, Romney asked if he could speak with Christie. The Republican governor, however, was in the air at the time returning from a Montana fundraiser and called Romney when he landed.
Romney, he said, asked Christie to be the keynote speaker at the Republican National Convention but said he had gone another direction in his running mate choice.
Christie said Monday he was not disappointed by the decision. "I told everyone all along I didn't want to be V.P."
He added: "I never really thought I was going to be asked, and I was right."
Christie became a major surrogate for Romney after he endorsed the former Massachusetts governor in October last year.
The New Jersey Republican first responded to the selection of Ryan the same day the House Budget Committee chairman was picked.
"With Paul Ryan on the ticket this is a team that understands the economic stagnation our country has been facing the last four years and the urgency with which we need to change course. The Romney-Ryan team is uniquely positioned to make the tough choices necessary to confront our fiscal challenges and get results," Christie said in a statement on Aug. 11.
