Retired coal miners and labor union opponents of Obama-era taxes on high-cost health plans came away with big wins in weekend negotiations by top congressional leaders and the Trump White House. The bill would also increase the age nationwide for purchasing tobacco products from 18 to 21, and offers with business-friendly provisions on export financing, flood insurance and immigrant workers.

The legislation would forestall a government shutdown this weekend and give President Donald Trump steady funding for his U.S.-Mexico border fence. The year-end package is anchored by a $1.4 trillion spending measure that caps a difficult, months-long battle over spending priorities.

The roster of add-ons grew over the weekend to include permanent repeal of a tax on high-cost "Cadillac" health insurance benefits and finance health care and pension benefits for about 100,000 retired union coal miners threatened by the insolvency of their pension fund. A tax on medical devices and health insurance plans would also be repealed permanently.

The deficit tab for the package grew as well — almost $400 billion over 10 years to repeal the three so-called "Obamacare" taxes alone — with a companion package to extend several business-friendly tax breaks still under negotiation. The Obama-era taxes have previously been suspended on a piecemeal basis.
