Christie says it's up to the former Massachusetts governor to make announcements about VP contenders and keynote speakers at the Republican National Convention. A Romney announcement could come as soon as Thursday according to some political observers.
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.
"All this speculation occurs because Gov. Romney is taking his time and being deliberative," Christie said.
The Philadelphia Inquirer reported Tuesday that Christie will be on the campaign trail through the end of the week in California, Washington and Montana, with no public events planned next week after his return to New Jersey.
