Democratic National Committee Chairman Tom Perez on Wednesday expressed his support to members of the United Auto Workers in Buffalo.

Across the country, 50,000 union workers from General Motors have been on strike since Sunday night — roughly 3,000 in Western New York alone.

"I'm here to speak for every Democrat to say we have your back," Perez said.

The former Secretary of Labor under President Barack Obama pointed out the previous administration bailed GM out a decade ago.

"In the course of that, the GM workers said we will share the sacrifice because we understand that these are tough times, but in return that basic bargain is when times get better then we should share in the prosperity and times are undeniably better. Look at their balance sheets," he said.

Perez said the auto company continues to benefit from federal assistance like the 2017 Republican tax cut bill. He criticized GM for shifting health insurance costs to the union this week.

"That was dirty pool and that's not going to help get them to the table. These folks have strength," he said. "They have a steely resolve."

Perez called for a fair resolution for auto workers but also questioned President Donald Trump's ability to mediate an agreement between the two parties.

"This is a president who doesn't keep promises and this is a president who just nominated a labor secretary who has a long record of stabbing unions in the back, making it harder for unions to organize," he said.

The chair said Trump and Labor Secretary nominee Eugene Scalia have a clear anti-union record.
