DIMONDALE -- A handful of Hillary Clinton supporters gathered outside the venue where Donald Trump will speak Friday evening, saying the Republican nominee would be bad for Michigan workers.

"If elected, Donald Trump would be a disaster for Michigan," said former U.S. Rep. Mark Schauer, a Democrat.

He said that Trump will likely say he's with Michigan workers at the rally later, but it's not true.

Trump has made manufacturing and trade deals -- specifically opposition to NAFTA and TPP -- a centerpiece of his economic message. In a Detroit speech last week he promised to help middle-income Americans where Democrats had failed them.

But Mike Green, president of the UAW Local 652, said on Friday Trump had shown time and time again that he was bad for workers.

"You look at records, his record against Hillary's record, she's always stood for working families. He never has. He don't know what a working family is. He's never been in one, he's never had to. So don't tell me about a working family, you don't understand it," Green said.

Clinton also opposes TPP and NAFTA. But her supporters on Friday said she could be trusted, while Trump couldn't. They pointed to people selling Trump merchandise outside the event with boxes that said "made in China" on the sides.

Mike Huerta, an autoworker of UAW Local 602, said that Trump had outsourced much of his own business to other countries, alleging Trump made his living in part through "slave wages" in other countries.

Trump is slated to speak in Dimondale at the Summit Sports and Ice Complex at 5 p.m.
