Labor Secretary Alexander Acosta is stepping down after criticism over his role in a nonprosecution deal reached years ago with the well-connected businessman accused of sex crimes, Jeffrey Epstein.

Acosta appeared on Friday at the White House with President Trump and announced his resignation.

"I do not think it is fair for this administration's Labor Department to have Epstein as its focus rather than the incredible economy we have today," Acosta said. "The right thing was to step aside."

Labor Secretary Alex Acosta defended a 2008 plea agreement he oversaw as a U.S. attorney in Florida in which multimillionaire and accused sex trafficker Jeffrey Epstein got a light sentence in exchange for pleading guilty to state charges.

"Facts are important, and facts are being overlooked," Acosta told reporters at a news conference Wednesday.
