A bipartisan group of senators has agreed that a spending package for Israel and Ukraine should include a measure making it more difficult to be granted asylum in the United States. It is not clear whether the idea will survive round of negotiations to finalize the national security spending measure, which could reach the Senate floor as soon as next week.

A group of senators led by Senator Alex Padilla, Democrat of California, called the proposals under discussion “harmful” and said they would “potentially deny lifesaving humanitarian protection for vulnerable people, including children, and fail to deliver any meaningful improvement to the situation at the border. Top Republicans have been adamant that stringent measures to crack down on border crossings between Mexico and the United States must accompany any assistance for Ukraine’s war against Russia. Democrats and Republicans are also discussing whether to expand requirements that asylum seekers apply for protections in “safe third countries” they pass through on the way to the United States, or risk expulsion to those countries. But Republicans are also seeking far more aggressive steps, including changes to parole, the practice of allowing migrants who may not be eligible for U.S. residency to be released from detention into the country for a temporary period. They want to reinstitute an array of Trump-era policies, including family detention and protocols that forced individuals who could not be held in detention facilities to wait in Mexico until it is their turn to appear in immigration court.
