Republican presidential candidate Mitt Romney says New Jersey Gov. Chris Christie would be on anybody's short list for a vice presidential running mate. Romney calls Christie an "extraordinary person" and "one of the leading figures in the Republican party."

The two appeared together on NBC's "Today" show _ and pointedly didn't reject running mate rumors _ the day after Christie handed Romney his endorsement. Asked if Christie would make a good match for a ticket with him, Romney said the two are great friends who agree on a host of issues.

Christie, who had considered running for president himself, says he hasn't been promised a spot on the ticket, or anything else, in return for his endorsement.
