LAKE WORTH, Fla. — As Donald Trump marks the grand opening of his new D.C. hotel, Hillary Clinton sharply criticized him for relying on undocumented labor to make the project cheaper.

“Today he’s in Washington, D.C., to open a new luxury hotel. While the hotel may be new it’s the same old story,” Clinton said at a rally at Palm Beach State College. “He relied on undocumented workers to make his project cheaper.”

Trump’s new downtown D.C. hotel was built thanks to the efforts of a large workforce that included Hispanic construction workers, including some workers who say they are undocumented, The Washington Post reported.

“We know he’s used undocumented workers. And that’s one of the things he’s run his campaign on, about deporting undocumented workers.”

In The Post's report, a Trump spokeswoman said the company and its contractors follow all applicable laws.

Clinton also criticized Trump for using products in his rooms that were made oversees and for suing the city over a high tax bill, and for using Chinese steel in stead of American steel for his real estate projects

"You can talk a good game but let’s look at the facts, and the facts show that he has stiffed American workers," Clinton said.

Later on Wednesday, Clinton will appear in Tampa with chef José Andrés, who had originally been slated to open a restaurant in Trump’s D.C. hotel.

Andrés “had the courage to stand up to Donald Trump about his divisive anti-immigrant views by refusing to put his restaurant in Trump’s hotel,” Clinton told the crowd.
