(CNN) -- New Jersey Gov. Chris Christie blasted Democrat Mary Burke on Monday, saying the Wisconsin gubernatorial hopeful can't be trusted after her campaign hired a political consultant who appeared to plagiarize parts of her job plan from other candidates. "I don't think they were teaching plagiarism at Harvard Business School. I don't think they were teaching you to cut and paste other peoples' work and call it your own," Christie said at an event for Republican Gov. Scott Walker in Hudson, Wisconsin. Burke, a former Trek Bicycle executive who has a business degree from Harvard, fired consultant Eric Schnurer earlier this month after BuzzFeed reported that portions of her jobs plan were apparently plagiarized from former candidates in other states.
