President Donald Trump is traveling to Michigan to promote his efforts to boost U.S. manufacturing. On Tuesday, Trump will tour a Ford factory in suburban Detroit and address the Detroit Economic Club. He plans to speak on his administration's efforts to spur domestic production and create jobs. After weak off-year elections for Republicans in November, Trump hit two other swing states, Pennsylvania and North Carolina, and gave speeches there last month to emphasize his economic policies. Democrats are criticizing his visit, highlighting concerns about affordability and health care.
