WASHINGTON • A $13.6 billion emergency package of military and humanitarian aid for besieged Ukraine and its European allies easily won final congressional approval Thursday, hitching a ride on a governmentwide spending bill that’s five months late but loaded with political prizes for both parties.

With Russian President Vladimir Putin’s invasion killing thousands and forcing over 2 million others to flee, the Senate approved the overall $1.5 trillion overall legislation by a 68-31 bipartisan margin.

Democrats and Republicans have battled this election year over rising inflation, energy policy and lingering pandemic restrictions, but they’ve rallied behind sending aid to Ukraine, whose stubborn resilience against brutal force has been inspirational for many voters.

“We promised the Ukrainian people they would not go at it alone in their fight against Putin,” Senate Majority Leader Chuck Schumer, D-N.Y., said just before the vote.

The House passed the compromise bill easily Wednesday. President Joe Biden’s signature was certain.

Around half the $13.6 billion measure was for arming and equipping Ukraine and the Pentagon’s costs for sending U.S. troops to other Eastern European nations skittish about the warfare next door. Much of the rest included humanitarian and economic assistance, strengthening regional allies’ defenses and protecting their energy supplies and cybersecurity needs.

Republicans backed that spending. But they criticized Biden for moving too timidly, such as in the unresolved dispute with Poland over how that nation could give MiG fighter jets to Ukraine that its pilots know how to fly.

“This administration’s first instinct is to flinch, wait for international and public pressure to overwhelm them,” said Senate Minority Leader Mitch McConnell, R-Ky.

White House aides told Congress last month that Biden wanted $6.4 billion to counter Russia’s invasion. He ended up formally requesting $10 billion, an amount that it took an eager Congress just a few days to boost to its final figure of $13.6 billion. The $1.5 trillion bill carrying that aid gave Democrats a near 7% increase for domestic initiatives, which constituted a bit less than half the package.
