Senators are struggling to strike a long-elusive compromise on US-Mexico border policy that Republicans insist is needed for assistance to Ukraine to pass Congress. Hardliners in the House gambled that they could leverage the assistance Ukraine says it desperately needs — as well as win a long-sought shift in US politics on immigration — to force Democrats’ hand on asylum restrictions and other Republican border priorities.

Republicans are looking to limit one of the Biden administration's tools for managing the border and helping with humanitarian escapes.

Senators are at an impasse in their negotiations on a bipartisan border security deal to be included in President Joe Biden’s supplemental defense spending bill.
