WASHINGTON — President Donald Trump is rallying support for the Republican health care overhaul by taking his case directly to GOP lawmakers at the Capitol, two days before the House plans a climactic vote that poses an important early test for his presidency.

At a rally Monday night in Louisville, Ky., Trump underscored what he called “the crucial House vote.”

“This is our long-awaited chance to finally get rid of ObamaCare,” he said of repealing former President Barack Obama's landmark law, a GOP goal since its 2010 enactment.

Trump's closed-door meeting with House Republicans was coming as party leaders released 43 pages worth of changes to a bill whose prospects remain dicey. Their proposals were largely aimed at addressing dissent that their measure would leave many older people with higher costs.

Included was language paving the way for the Senate, if it chooses, to make the bill's tax credit more generous for people age 50-64. Details in the documents released were initially unclear.

Older and disabled Medicaid beneficiaries would get larger benefits. But it would also curb future growth of the overall Medicaid program, which helps low earners afford medical coverage, and let states impose work requirements on some recipients. Additional states could not join the 31 that opted to expand Medicaid to more beneficiaries under Obama's law, the Affordable Care Act.

Republican support teetered last week when a nonpartisan congressional analysis projected the measure would strip 24 million people of coverage in a decade.
