The debate over Ukraine aid was already complicated. Then it became tangled up in US border security

WASHINGTON (AP) — As war and winter collide, a top adviser to Ukrainian President Volodymyr Zelenskyy acknowledged during a recent visit to Washington that the days ahead “will be tough” as his country battles Russia while U.S. support from Congress hangs in the balance.

President Joe Biden’s nearly $106 billion aid package for Ukraine, Israel and other needs sits idle in Congress, neither approved nor rejected, but subjected to new political demands from Republicans who are insisting on U.S.-Mexico border policy changes to halt the flow of migrants.

Linking Ukraine’s military assistance to U.S. border security interjects one of the most divisive domestic political issues — immigration and border crossings — into the middle of an intensifying debate over wartime foreign policy.

When Congress returns this coming week from the holiday break, Biden’s request will be a top item on the to-do list, and the stakes couldn’t be higher. Failure risks delaying U.S. military aid to Kyiv and Israel, along with humanitarian assistance for Gaza, in the midst of two wars, potentially undermining America’s global standing.
