President Donald Trump's tax cut and spending bill faces a critical stress test on Wednesday as Republicans in the U.S. House of Representatives try to overcome internal divisions about cuts to the Medicaid health program and tax breaks in high-cost coastal states.

The struggle to pass Donald Trump’s second-term agenda in Congress has never been between Republicans and Democrats; the minority party has had little real role so far.

"The President also made it clear he’s losing patience with all holdout factions of the House Republican Conference, including the SALT Caucus and the House Freedom Caucus," the official said.
