The Republican tax plans are suddenly looking a lot more like health-care bills, with provisions that may affect coverage and increase medical expenses for millions of families.

The House version of the tax bill, which President Donald Trump endorsed on Tuesday, would end a deduction that allows families of disabled children and elderly people to write off large medical expenses. The Senate plan would repeal the Obamacare requirement that most Americans carry insurance, a move that insurers promise would raise premiums in the nationwide individual insurance market.

The provisions would help offset the cost of large tax cuts for corporations and individuals. But the move has sparked a new wave of opposition from the health-care industry and others who are concerned about its impact -- the same political headwinds that tanked Republican efforts to repeal the Affordable Care Act earlier this year.
