TRENTON, N.J. (AP) — On a day of renewed chatter over whether New Jersey Gov. Chris Christie might still be on Mitt Romney’s radar as a possible running mate, Christie is saying little.

Christie says it’s up to the former Massachusetts governor to make announcements about VP contenders and keynote speakers at the Republican National Convention.

Christie has been rumored to be in the running for both spots. He heads to California to raise money for Romney Wednesday, the same day the presumptive GOP presidential nominee makes a fundraising stop in New Jersey.

Speculation had all but died out about the brash first-term governor being picked to join the Republican ticket.

But when Christie’s name wasn’t on the list of seven GOP convention speakers announced Monday, a new round of speculation began.
