WASHINGTON — Congressional Republicans are pressing for an end to the four-decade ban on exporting crude oil and further curbs on President Obama’s environmental agenda as part of a sweeping $1.1 trillion spending bill.
Days from a Friday midnight deadline, progress has proven elusive for negotiators who also are trying to hammer out a separate measure to renew expired tax breaks. The two bills are the major item of unfinished business for this session of Congress.
While the GOP is seeking concessions from the Obama administration and Democrats on the environment, Republicans have dropped demands to cut off federal funds for Planned Parenthood and for implementing Obama’s marquee health care law.
The spending bill would fill out the details of the October budget deal and fund the day-to-day operating budgets of every Cabinet agency, averting a partial government shutdown.
House Speaker Paul Ryan said Monday that Congress may miss the deadline to complete the bill and renew a growing package of tax breaks for businesses and individuals.
‘‘It might take us more than just this week to get these issues put together correctly,’’ Ryan told a radio station in Janesville, Wis., after negotiations over the weekend failed to close out numerous unresolved items.
The bills’ fates have become intertwined as part of a negotiation among leaders like Ryan, Senate majority leader Mitch McConnell, and Democrats Harry Reid and Nancy Pelosi.
The tax measure would renew dozens of tax breaks that typically are renewed a year or two at a time. This year, both sides are working to make some of them permanent, which is proving tricky to do. Democrats hope to use repeal of the oil export ban as a bargaining chip.
Most of the spending items in the so-called omnibus appropriations bills have been worked out, but numerous difficult policy provisions remain, including a GOP bid to block new emissions rules for power plants and an effort to restrict Obama’s ability to declare national monuments in his final year in office.
