WASHINGTON (AP) — President Donald Trump is set to meet with congressional leaders from both parties to discuss his agenda, as he enters his first official week in the White House and works to begin delivering on his ambitious campaign promises. There's a breakfast and what the White House calls a listening session with business leaders in the morning; another listening session with union leaders and workers in the afternoon; and a reception later on with the members of Congress he'll need on board to overhaul the nation's health care system, among other goals. The outreach effort comes after a tumultuous first weekend in the White House that included lambasting news organizations for correctly reporting on the size of the crowds at his inauguration and mass protests against his presidency on the following day. Speaking in the White House East Room during a swearing-in ceremony for top aides, the president warned his staff of the challenges ahead but declared he believed they were ready. The prime minister said he is hoping to forge a "common vision" with the newly inaugurated U.S.
