Bill Clinton's Pennsylvania-Made Shirt Takes Center Stage at Clinton-Kaine Rallies

Hillary Clinton used it to illustrate her commitment to U.S.-made products.

Clinton then worked her husband's shirt into the speech, saying, "In fact, my husband told me on the bus ride here ... you know, this shirt he has on right now, he said, that's made in Reading, Pennsylvania. And, look. You're not going to believe this because it just sounds too coincidental. It's made at a company called Bills. So Donald Trump says he wants to make 'America Great Again.' Well, he can start by actually making things in America again!"

Bill Clinton proceeded to unbutton his blazer to show off the plaid shirt.

Hillary Clinton retold the tale of the Pennsylvania-made shirt at her next rally, in Pittsburgh, Pennsylvania.

"When we were packing for the bus tour, he said, 'What am I supposed to wear? I said well I don’t know, it’s sort of 'bus tour casual.' And so you know, he’s going through his closet and this morning in the hotel in Harrisburg he’s putting this shirt on, he goes 'you know what?' This shirt was made in Reading, Pennsylvania. And you will not believe this, at a company called Bills."

During the event, he tweeted a photo of his shirt's label, confirming it was made in the Keystone State.

And finally, at a rally later in the day in Youngstown, Ohio, Hillary Clinton, said, "I don’t ant to stir up any rivalry with Pennsylvania, but my husband is wearing a shirt that was made in Reading, Pennsylvania. So if we’re going to start making things in America, Donald Trump better start making things in America."
