President Donald Trump on Saturday marked his 100th day in office by saying he had brought "profound change" to Washington and reaffirming that "my only allegiance" is to those he governs. During an evening trip to Pennsylvania, one of the states that propelled his unlikely election victory, Trump planned to sign an executive order directing the Commerce Department and the U.S. trade representative to conduct a study of U.S. trade agreements.
