R. Alexander Acosta, President Donald Trump’s nominee to be secretary of the U.S. Labor Department, said Wednesday he would follow the president’s Feb. 3 executive order directing the agency to review its fiduciary rule.

Noting the Labor Department’s current proposal to delay for 60 days the effective date of the fiduciary rule — from April 10 to June 9 — Sen. Elizabeth Warren, D-Massachusetts, queried Acosta during his confirmation hearing before the Senate Health, Education, Labor and Pensions Committee on whether, if confirmed before the delay is finalized, he would “promise to stop” such a delay.
