Coal-state lawmakers say Congress is close to a deal to extend health benefits for more than 22,000 retired miners and widows whose medical coverage is set to expire Sunday. GOP Speaker Paul Ryan and top House Democrat Nancy Pelosi are at odds over a demand by Democrats to use the must-do measure to guarantee that payments continue to flow under the health care law to help low-income beneficiaries with out-of-pocket costs. [...] an influential GOP House moderate is opposing the proposal, leaving party leaders to assess whether the idea could help one of President Donald Trump's premier but most problematic priorities spring back to life. Republican lawmakers were meeting Wednesday to consider how to rescue the GOP drive to repeal much of President Barack Obama's health care law. While erasing Obama's statute is solidly opposed by Democrats, the budget measure will need support from both parties because GOP conservatives often oppose spending legislation.
