New Jersey Gov. Chris Christie, who is campaigning Monday in Hudson, Wis., for Gov. Scott Walker's re-election bid, also has plans to campaign for Jeff Johnson in Minnesota in two weeks. 

Johnson's campaign confirmed Monday that Christie, the chairman of the Republican Governors Association, would appear with Johnson on Oct. 13. Spokesman Jeff Bakken said details of the event are still being worked out and would be released later. 

Christie, the second-term governor of New Jersey, is seen as a competitor for the 2016 GOP presidential nomination though he saw his reputation tarnished by a local scandal earlier this year.

On Monday, Christie and Walker are touring Empire Bucket, a manufacturing firm in Hudson. Walker is in a tough re-election fight against Democrat Mary Burke. 

Johnson is not attending the event across the St. Croix River from the Twin Cities. Bakken said he is fundraising. 

Christie campaigned for the last Republican candidate for governor in Minnesota, appearing at a Blaine rally for Tom Emmer in 2010.
