U.S. lawmakers began departing Washington on December 14 without a deal to send more military aid to Ukraine, even as President Joe Biden's administration raced to negotiate with Senate Republicans who are demanding changes to U.S. border security policy. The Senate planned to come back next week in hopes of finalizing a deal to place new restrictions on asylum claims at the U.S. border and pass the $110 billion package of aid for Ukraine and Israel and other national-security needs. But the House of Representatives showed no sign of returning to push the legislation through the full Congress.
