WASHINGTON (AP) — The Senate slogged through a tense overnight session that dragged into Tuesday, with Republican leaders searching for ways to secure support for President Donald Trump’s big bill of tax breaks and spending cuts while fending off proposed amendments, mostly from Democrats trying to defeat the package.
