WASHINGTON — President Trump’s latest threat to pull financing for ObamaCare has rattled Democrats and met GOP reluctance in Congress.

Trump is openly pondering axing funding for ObamaCare subsidies – worth an estimated $7 billion a year—to get Democrats to the table to negotiate on a repeal and replacement plan.

Democrats balked at Trump’s attempts to end funding — known as Cost Sharing Reduction payments — as political blackmail.

“Withholding these payments is a blatant attempt to undermine the Affordable Care Act and manufacture a crisis,” said Rep. Joseph Crowley (D-Queens). “…Democrats will not be held hostage by President Trump’s petty partisan games.”

Sen. Charles Schumer (D-Brooklyn) said if Trump drops repealing ObamaCare, Democrats would be willing to talk improvements to healthcare.

But threatening to put the healthcare market in a tailspin and jeopardizing Americans healthcare is a failing political ploy, Schumer said.

“This cynical strategy will fail,” Schumer said.

Even the Republican leadership is not on board.

Speaker Paul Ryan stands by his comments from March that the payments should be continued.

Former House Speaker John Boehner filed suit against the Obama Administration in 2014, in attempt to halt the cost-sharing subsidies that go to insurers to help low-income patients pay for medical bills.

House Republicans argued the subsidies are illegal since they weren’t authorized by Congress. A federal judge sided with the Republicans, but suspended her ruling to let the Obama Administration appeal.

It’s now up to the Trump Administration to decide whether keep up the fight.

In an interview with the Wall Street Journal, Trump said if he doesn’t back the subsidies and Congress refuses to vote to fund them, ObamaCare is dead.

“That would mean that ObamaCare doesn’t have enough money so it dies immediately as opposed to over a period of time … This is a very big deal that nobody even understands,” Trump said.

Given his power to block subsidies, Trump said Schumer [and other Democrats] “should be calling me up and begging me to help him save Obamacare.”

But Ryan doesn’t want to pull the plug as the lawsuit is still pending.

“While the lawsuit is being litigated, then the Administration funds these benefits. That’s how they’ve been doing it, and I don’t see any change in that,” Ryan said last month.
