WASHINGTON, July 3 (Reuters) - Republicans in the U.S. House of Representatives advanced President Donald Trump 's massive tax-cut and spending bill toward a final yes-or-no vote early on Thursday morning, appearing to overcome internal party divisions over its cost.

The tight roll call, 218-214, came at a potentially high political cost, with two Republicans joining all Democrats opposed.

The Republican package would slash taxes, boost spending on immigration enforcement and the military, and impose steep cuts to Medicaid, SNAP and clean energy funding.
