Nov. 11 (UPI) -- Senate Republicans have signaled that they are willing to negotiate with Democrats on healthcare subsidies, but are demanding tighter abortion rules on insurance plans.

Senate Republican Leader John Thune described his party's negotiating position to reporters before the chamber passed a bill on Monday to reopen the government, according to NBC News. Thune's remarks set the stage for the next partisan fight over expiring health care subsidies that were at the center of the longest government shutdown on record.

Sen. Ron Wyden, D-Ore., sharply criticized the Republican proposal in a floor speech Saturday, calling it "a backdoor national abortion ban."

"Democrats must dismiss this radical Trojan horse against women's essential healthcare out of hand," he said.
