(Bloomberg) -- President Donald Trump named former NationalLabor Relations Board member R. Alexander Acosta as his newnominee for labor secretary, the first Hispanic he haschosen for his cabinet.

Trump said Acosta will be "a tremendous secretary of labor."

Acosta replaces Trump’s first nominee for the position, AndyPuzder, who withdrew his name Wednesday amid controversy over hispersonal life and business background.

Acosta served as assistant attorney general for the Civil RightsDivision under President George W. Bush and was U.S. attorney forthe Southern District of Florida. He once clerked for then-AppealsCourt judge Justice Samuel Alito, Jr.

He is currently the dean of Florida International University andthe chairman of U.S. Century Bank.

He met with Trump Wednesday evening, a White House officialsaid.

“He’s intense, hardworking, but I think in contrast to Puzder,he’s going to get things done more quietly,” said Tammy McCutcheon,who served as administrator of the Wage and Hour Division of theLabor Department during the Bush administration. “He will bequietly efficient. I don’t think you’ll see a lot of difference inhis policy positions from Puzder.”

Puzder, a fast-food executive who had beenscheduled for a Senate confirmation hearing Thursday, ran intotrouble in the Senate over his admission that he employed anundocumented housekeeper.
