Manufacturers in the U.S. are cutting thousands of jobs even as Trump pushes economic policies that he says will revitalize the industry.

Employers shed 12,000 manufacturing jobs in August, while payrolls in the sector have shrunk by 42,000 since April, according to a new analysis from the Center for American Progress (CAP) that draws on government labor data.

The nonpartisan policy institute attributes that decline to the Trump administration’s steep new tariffs; hardline stance on immigration; and the Republican-backed “big, beautiful bill,” a tax and spending package enacted by Mr. Trump in July that CAP says hurts renewable energy companies by phasing out certain tax credits.
