Earlier this year, Foxconn said it was rethinking its plans, citing “new realities” in the market. Even before then, the company had hinted that its Wisconsin project would focus more on research and development, rather than on the intensive factory work that tends to generate blue-collar jobs.

Foxconn said at the time that it would hold to its pledge to create 13,000 jobs, telling The New York Times that 25 percent of its Wisconsin employees would be focused on manufacturing. Soon after, following a conversation between Mr. Trump and Terry Gou, Foxconn’s billionaire founder, the company said it still intended to build a plant to produce displays for consumer products.

Mr. Gou announced plans on Wednesday to run for Taiwan’s presidency. Mr. Trump has praised his business acumen, calling him “one of the great businessmen of our time.” His company did not immediately respond to a request for comment.

“The present contract deals with a situation that no longer exists, so it’s our goal to make sure that the taxpayers are protected and environmental standards are protected,” Mr. Evers said. “And we believe we need to take a look at that contract and see if it needs to be downsized as a result.”
