"He wears it like a crown — Make America Great Again — but Trump made his shirts in Bangladesh, his ties in China and his suits in Mexico," says a narrator in a 30-second video ad. 

"So don't believe the hat. You can't make America great again if you don't make things in America." 

The ad is set to air in the key battleground states of Pennsylvania, Iowa, Ohio, North Carolina and Florida.

The clip is just the latest attack by Clinton on Trump's business record. The Democratic nominee frequently hits Trump on the campaign trail for making some of his products in other countries. 

"Now, before he tweets about how he's really one who'll put 'America First' in trade, let's remember where Trump makes many of his own products. Because it's sure not America," Clinton said in a speech Michigan earlier this month.
 
"He's made Trump ties in China and Trump suits in Mexico instead of here in Michigan. He keeps saying it's not possible to make these things in America anymore. That's just wrong."
