The Senate, with a 67-32 vote, agreed to debate this version of the bill, which excludes immigration enforcement measures previously included.

While Senate Majority Leader Chuck Schumer has called the vote a positive step, the bill's final approval remains uncertain, as Republicans like Senator Rand Paul promise to slow down its progress with procedural delays.

Despite the setback, domestic political dynamics complicate the bill's future. After a failed attempt to integrate border security into the legislation, the bill now faces potential hurdles in the House, where Republicans are increasingly reluctant to provide further aid to Ukraine.

House Democrats, however, are determined to push through comprehensive national security legislation. Should the Senate approve the bill, it will then be up for negotiation in the House, where the outcome is less predictable due to a narrow Republican majority and a growing faction opposing additional Ukrainian support.
