WASHINGTON — Heralding a "new chapter of American greatness," President Donald Trump stood before Congress for the first time Tuesday night and issued a broad call for overhauling the nation's health care system, significantly boosting military spending and plunging $1 trillion into upgrading crumbling infrastructure. Striking an optimistic tone, Trump declared: "The time for small thinking is over." Trump's address came at a pivotal moment for a new president elected on pledges to swiftly shake up Washington and follow through on the failed promises of career politicians.
