Gov. Chris Christie to campaign for Gov. Walker in Wisconsin

MADISON (AP) — New Jersey Gov. Chris Christie is coming to Wisconsin to campaign for fellow Republican Gov. Scott Walker later this month.

A spokesman for the Republican Governors Association confirmed Wednesday that Christie was coming on Sept. 29, but said details of the visit are still being worked out. A spokeswoman for Walker's campaign did not immediately return a message.

Walker is in a tight re-election contest against Democrat Mary Burke, a former Trek Bicycles executive and state Commerce Department secretary.

Christie and Walker are both mentioned as potential 2016 Republican candidates for president.

While they could be potential rivals, they have also spoken highly of one another over the years. Christie is chairman of the Republican Governors Association and previously campaigned for Walker in Wisconsin in 2012.
