WASHINGTON:  Debate is underway in the Senate for an all-night session Sunday, with Republicans wrestling President Donald Trump’s big bill of tax breaks and spending cuts over mounting Democratic opposition — and even some brake-pumping over the budget slashing by the president himself.

The outcome from the weekend of work in the Senate remains uncertain and highly volatile, and overnight voting has been pushed off until Monday.

GOP leaders are rushing to meet Trump’s Fourth of July deadline to pass the package, but they barely secured enough support to muscle it past a procedural Saturday night hurdle in a tense scene.
