U.S. Senator Patty Murray blistered Andrew Puzder, President Trump’s nominee for U.S. Secretary of Labor, for Puzder’s opposition on overtime pay and raising the minimum wage at a press conference Thursday.

“Puzder has spoken out against raising the minimum wage and against efforts to help more workers get overtime pay. He thinks robots would be more convenient for employers than actual workers, because robots never get sick or need a lunch break,” said Murray (D-WA), the top Democrat on the Senate labor committee.

Puzder has been CEO of CKE Restaurants since September 2000, the parent company of the fast-food chains of Carl’s Jr. and Hardee’s.

Murray called out Pudzer for the racy advertisements that have brought much publicity, and much controversy, to Hardee’s.

“Mr. Puzder’s vocal defense of his deeply offensive ads — and so much more about his background — raise serious questions in my mind about his ability to represent the rights of women in the workplace, as any Secretary of Labor absolutely must be able to do,” Murray said.

Murray, Washington state’s senior senator, was joined at the press conference by fast food workers and other opponents of Puzder’s nomination. She said Puzder has a history of squeezing workers while heading CKE Restaurants and has fought policies that would help workers.

Last month, Murray and Sen. Elizabeth Warren (D-MA) released a report that documented worker mistreatment at chain restaurants operated by CKE. They also hosted a Senate forum where workers shared stories of poor working conditions, lost wages and overtime violations.

“Workers like Angel have told absolutely horrific stories of lost wages, overtime violations, harassment, and more at chain restaurants Puzder oversaw at CKE — the kinds of issues that if confirmed, he’ll be responsible for investigating … all of this adds up to a nominee for Secretary of Labor who is uniquely unqualified,” Murray said.

Murray also called out Puzder for not paying taxes, and said it was a “disqualifying” issue.

“This week, we learned that for years, President Trump’s selection for the Department of Labor admitted that he failed to pay taxes on a worker he employed. And he only chose to pay those taxes once he had the chance to be part of the Trump Cabinet,” Murray said.

“To me, it is shocking that a nominee for this critical position would flout these rules so openly — overlooking the same responsibilities that business owners nationwide manage to uphold,” she said. “So I agree with Senator Schumer that not only is Andrew Puzder uniquely unqualified — but his decision to pick and choose what laws he himself follows is disqualifying.”

A nomination hearing for Puzder has been scheduled for Thursday, Feb. 16.
