TRENTON — Gov. Chris Christie is off to Colorado next week for a speaking engagement at the Aspen Institute with four other prominent Republican governors.



He will join Govs. Nikki Haley of South Carolina, Bobby Jindal of Louisiana, Bob McDonnell of Virginia and Scott Walker of Wisconsin. Walter Isaacson, CEO of the nonprofit education and policy studies organization based in Washington, will moderate the Wednesday evening conversation.



They'll be in town for the Republican Governors Associations' Executive Roundtable quarterly meeting, which has been held in Aspen since 2009, said RGA spokesman Mike Schrimpf.



All five governors have generated buzz at one time or another as potential running mates for presumptive presidential nominee Mitt Romney, who said Wednesday he won't make any announcements while on an overseas trip.



Christie, who is vice chair of the RGA, has shared stages with his colleagues recently. Jindal spoke at a regional Conservative Political Action Conference headlined by Christie in June and he hit the campaign trail for Walker in May. Isaacson, former editor of TIME magazine, wrote the recent best-selling biography of Steve Jobs.
