Democrats in the Senate are pushing to advance a package that would send billions of dollars in aid to Ukraine and Israel, after Republicans blocked similar legislation that paired the foreign aid with stringent border security measures.

A vote on the measure is expected later this evening.

Members of both parties have privately said that they believe the legislation could eventually receive support from at least 60 senators, putting the measure on track to pass in the Senate within days. The bill would send about $60 billion to Ukraine for its war against Russia, $14 billion in security assistance to Israel and $10 billion in humanitarian aid for civilians in global crises, including Palestinians and Ukrainians.

But even if lawmakers succeed in resurrecting the aid bill in the Senate, it still faces stiff headwinds in the Republican-led House, where right-wing lawmakers oppose sending additional assistance to Ukraine. Some have even threatened to oust Speaker Mike Johnson if he brings any bill to the floor that includes aid for Ukraine.

The effort to revive the aid was a glimmer of hope for members of both parties who have warned that the fate of Eastern Europe — and America’s reputation on the world stage — hang in the balance if Congress fails to move ahead.
