WASHINGTON - President Donald Trump's plan to replace the Affordable Care Act is expected to go up for a vote today in the House, but it will not be getting support from the city's only Republican member of Congress.

It's still not clear if the president will have enough votes to pass it.

Trump met with 18 GOP lawmakers at the White House Wednesday in a last-minute attempt to win support for the measure.

Vice President Mike Pence also made the rounds, while Republican leaders held numerous talks at the Capitol.

Some conservatives claim the bill doesn't go far enough in undoing the ACA.

They want to repeal of the law's requirements that insurers pay for specified services like maternity care, prescription drugs and substance abuse treatment.

Moderates are still concerned that the measure will leave too many people uninsured, and raise  out-of-pocket costs for many low-income and older Americans.

Every House Democrat is expected to vote no on the bill.

The measure would be defeated if 23 Republicans follow suit.

The Associated Press counted at least 26 Republicans who said they opposed it, or are leaning that way.

The city's only Republican Congressman, Dan Donovan, says he's voting "no" on the health care bill.

Donovan opposes a recent amendment by two upstate Republicans that would shift Medicaid costs from every county in the state except the five boroughs to Albany.

"That burden should not fall on the tax paying people of New York City, the taxpaying people of the 11th Congressional District in Brooklyn and Staten Island. And there's a fear that to make up the difference in the deficit of relieving those upstate communities, it would fall on our folks to the tune of about $300 million a year," Donovan said.

Donovan also says the measure will hurt two hospital systems on Staten Island and two others in Brooklyn, which are the largest employers in his district.

It was seven years ago Thursday that the Affordable Care Act was signed into law.

In a statement released by former President Barack Obama, he says the legislation achieved an insurance rate of 90 percent among Americans, the highest rate in American history.

President Trump campaigned on a promise to repeal the Affordable Care Act, saying it actually made healthcare more expensive and restricted personal choice.

Obama's statement says in part, "America is stronger because of the Affordable Care Act.  There will always be work to do to reduce costs, stabilize markets, improve quality, and help the millions of Americans who remain uninsured in states that have so far refused to expand Medicaid."
