Senate Negotiators Fail to Reach Agreement on Border Framework

WASHINGTON—Senate negotiators failed Sunday to reach a deal on a framework for border-security measures that Republicans have demanded as a condition of passing new funding for Ukraine, further slimming the chances of any vote before Christmas.

The lack of a breakthrough by the self-imposed weekend deadline underscored the difficulties facing the Senate talks, even after the Biden administration signaled it was prepared to make significant concessions on immigration policy. Many Republicans not involved in the discussions have expressed skepticism in recent days about any deal, and progressive Democrats have raised concerns that the White House was bowing to conservative demands.
