CLEVELAND — Donald Trump’s campaign is using American Apparel to manufacture some of its campaign merchandise selling at the Republican convention.

American Apparel came under government scrutiny in 2009 and was forced to fire 1,500 immigrant workers because they were unable to prove they had a legal right to work in the U.S.

A quick peek at some of the patriotic merchandise on sale at the Quicken Loans Arena here turned up the American Apparel labels. The company’s Made in U.S. and pro-immigrant stance are integral parts of its brand image. But the retailer is also said to be mulling outsourcing some of its apparel.

Trump, the Republican presumptive presidential nominee, has railed against immigrants, particularly Mexican immigrants, and outsourcing, building his campaign on a “Make America Great Again” theme.

At the same time, he has come under fire for his own signature suit and tie collection that have reportedly been made by licensees in China and Mexico.
