At least three major labor unions have endorsed President Trump’s new pick to head the Labor Department, Florida International University law school dean R. Alexander Acosta, a significant change from Trump’s previous pick, fast-food businessman Andrew Puzder, who was fiercely opposed by unions and Democrats.

Acosta has been endorsed by the International Union of Operating Engineers, the Laborers’ International Union of North America and the International Association of Fire Fighters. All praised his record of public service in the two previous presidential administrations and said they expected he would fairly apply the law as labor secretary.
