The US House of Representatives on Saturday with broad bipartisan support passed a $148 billion legislative package providing security assistance to Ukraine, Israel and Taiwan, over bitter objections from Republican hardliners.
The legislation now proceeds to the Democratic-majority Senate, which passed a similar measure more than two months ago. Final passage was expected sometime next week, which would clear the way for Biden to sign it into law.
The bills provide $94 billion to address the conflict in Ukraine, including $35 billion to replenish US weapons, stocks and facilities; $40 billion for Israel, including $14 billion for humanitarian needs, and $12.6 billion for the Indo-Pacific, including Taiwan.
Ukrainian President Volodymyr Zelenskyy expressed his thanks, saying US lawmakers moved to keep "history on the right track."
"The vital US aid bill passed today by the House will keep the war from expanding, save thousands and thousands of lives, and help both of our nations to become stronger," Zelenskyy said on X.
Unsurprisingly, Russia took the opposite view.
"It will further enrich the United States of America and ruin Ukraine even more, by killing even more Ukrainians because of the Kyiv regime," said presidential spokesman Dmitry Peskov, state news agency TASS reported.
It was unclear how quickly the new military funding for Ukraine will be depleted, likely causing calls for further action by Congress.
Biden, who had urged Congress since last year to approve the additional aid to Ukraine, said in a statement: "It comes at a moment of grave urgency, with Israel facing unprecedented attacks from Iran and Ukraine under continued bombardment from Russia."
Meanwhile, the House's actions during a rare Saturday session put on display some cracks in what generally is solid support for Israel within Congress. Recent months have seen progressive Democrats express anger with Israel's government and its conduct of the war in Gaza.
Saturday's vote, in which the Israel aid was passed 366-58, had 37 Democrats and 21 Republicans in opposition.
Passage of the long-awaited legislation was closely watched by US defence contractors, who could be in line for huge contracts to supply equipment for Ukraine and other US partners.
The unusual four-bill package also includes a measure that includes and the potential transfer of seized Russian assets to Ukraine.
