U.S. President Donald Trump swore in his new chief of staff, John Kelly, on Monday and sought to portray his White House as firing on all cylinders by pointing to the buoyant stock market and low unemployment rate.
Trump brought in Kelly, a retired Marine Corps general, after a chaotic week in which his first legislative effort - healthcare reform - failed in Congress, heightening concerns in his Republican Party that West Wing dysfunction would derail other priorities like tax reform.
