Trump fights for healthcare bill, makes headway with conservatives

(Adds Dent statement, meeting with moderates)

WASHINGTON, March 22 (Reuters) - U.S. President Donald Trump and House of Representatives leaders pushed on Wednesday for votes for their plan to overhaul Obamacare and said they were making progress in their efforts to win over conservative Republicans who have demanded changes to the legislation.

With a vote on the bill possible as soon as Thursday, members of the House Freedom Caucus, a conservative Republican faction, said they had been negotiating alterations to the plan with the White House.

Much of the discussion hinged on conservatives' desire to scrap what are labeled "essential health benefits" - services that insurance plans are required to cover under the Affordable Care Act, commonly called Obamacare, such as mental health help.

"I can tell you that we're making great progress," Mark Meadows, chairman of the hardline conservative House Freedom Caucus, told reporters. "We're not there yet. But we're hopeful."

Trump was to meet at the White House with members of the Freedom Caucus on Thursday at 11:30 a.m. (15:30 GMT), the White House said.

But while the president courted conservatives, the bill appeared to be losing traction among Republican moderates, some of whom attended a meeting late Wednesday in House Speaker Paul Ryan's office. Representative Charlie Dent, a leader of the "Tuesday Group" of House Republican moderates, issued a statement saying he could not back the bill.

"I believe this bill, in its current form, will lead to the loss of coverage and make insurance unaffordable for too many Americans, particularly for low- to moderate-income and older individuals," Dent said in the statement.

The chairman of the House Rules Committee, which met all day Wednesday to set the rules for the bill's consideration on the House floor, said late on Wednesday that the panel would resume its meeting on Thursday, having made no definite decision on the timing of the floor vote.

Repealing and replacing Democratic former President Barack Obama's 2010 Affordable Care Act is a first major test of Trump’s legislative ability and whether he can keep his big promises to business.

Plans aired by Trump during his election campaign and his first two months in office lifted U.S. stock markets to new highs. But stocks fell back sharply on Tuesday as investors worried that a rough ride for the healthcare legislation could affect his ability to deliver on other big pieces of his agenda, from cutting taxes and regulation to boosting infrastructure.
