President Donald Trump wasted little time in naming R. Alexander Acosta on Thursday as his new labor secretary nominee to replace Andrew Puzder, who withdrew his nomination amid opposition in the U.S. Senate.

Acosta is the dean of Florida International University in Miami and a veteran Republican administrator, serving as assistant attorney general for civil rights at the U.S Justice Department under President George W. Bush and later as the U.S. attorney in Miami. He is the son of Cuban immigrants.
