Coal miners seem to be at the center of the latest government shutdown concerns.
A stopgap spending bill to keep the government funded through April 28 passed overwhelmingly in the House on Thursday. The current spending plan expires midnight Friday.
But several Democratic senators, including Sen. Joe Manchin (D-W.Va.), are trying to convince the Senate to miss the bill's deadline. They want to continue negotiations with Republicans over extending medical benefits for miners.
Thousands of former union miners have been informed their health benefits will run out Jan. 1. And thousands more could face the same fate at a later date.
The House-approved stopgap bill only extends miners' health benefits for four months. Senate Democrats are demanding a vote to increase that to one year.
And they're hoping President-elect Donald Trump's support for coal country will put the heat on Republicans.
As incoming Senate Minority Leader Chuck Schumer told reporters: "I hope our new president-elect, who talked and got to know the miners, will speak out. We don't care about partisanship."
But Republicans say it's too late to negotiate. House members have already finished up their business and are heading home for the year. If lawmakers can't reach an agreement Friday, the government shutdown would start Saturday.
