With overwhelming support, the $61 billion in aid for Ukraine delivered a strong showing of American backing as lawmakers race to deliver a fresh round of U.S. support to the war-torn ally. Some lawmakers cheered on the House floor and waved blue-and-yellow flags of Ukraine.

The unusual process, with each bill having its own vote, allowed unique coalitions to form around the bills, pushing them forward. The whole package will go to the Senate, where passage in the coming days is nearly assured. President Joe Biden has promised to sign it immediately.

“We did our work here, and I think history will judge it well,” said embattled Speaker Mike Johnson, R-La., who is risking his own job to marshal the package to passage.

Biden, in a statement, thanked Johnson, Democratic leader Hakeem Jeffries and the bipartisan coalition of lawmakers “who voted to put our national security first.”

“I urge the Senate to quickly send this package to my desk so that I can sign it into law and we can quickly send weapons and equipment to Ukraine to meet their urgent battlefield needs,” the president said.

President Volodymyr Zelenskyy of Ukraine said he was “grateful” to both parties in the House and “personally Speaker Mike Johnson for the decision that keeps history on the right track,” he said on X.

“Thank you, America!” he said on X, formerly Twitter.

The weekend scene presented a striking display of congressional action after months of dysfunction and stalemate fueled by Republicans, who hold the majority but are deeply split over foreign aid, particularly for Ukraine as it fights Russia’s invasion. Johnson relied on Democratic support to ensure the military and humanitarian package won approval.

The morning opened with a somber and serious debate and unusual sense of purpose as Republican and Democratic leaders united to urge quick approval, saying that would ensure the United States supported its allies and remained a leader on the world stage. The House’s visitor galleries crowded with onlookers.

“The eyes of the world are upon us, and history will judge what we do here and now,” said Rep. Michael McCaul, R-Texas, chairman of the House Foreign Affairs Committee

Passage through the House cleared away the biggest hurdle to Biden’s funding request, first made in October as Ukraine’s military supplies began to run low. The GOP-controlled House struggled for months over what to do, first demanding that any assistance be tied to policy changes at the U.S.-Mexico order, only to immediately reject a bipartisan Senate offer along those very lines.

Reaching an endgame has been an excruciating lift for Johnson that has tested both his resolve and his support among Republicans, with a small but growing number now openly urging his removal from the speaker’s office. Yet congressional leaders cast the votes as a turning point in history — an urgent sacrifice as U.S. allies are beleaguered by wars and threats from continental Europe to the Middle East to the Indo-Pacific.

“Sometimes when you are living history, as we are today, you don’t understand the significance of the actions of the votes that we make on this House floor, of the effect that it will have down the road,” said New York Rep. Gregory Meeks, the top Democrat on the House Foreign Affairs Committee. “This is a historic moment.”

Opponents, particularly the hard-right Republicans from Johnson’s majority, argued that the U.S. should focus on the home front, addressing domestic border security and the nation’s rising debt load, and they warned against spending more money, which largely flows to American defense manufacturers, to produce weaponry used overseas.

Still, Congress has seen a stream of world leaders visit in recent months, from Zelenskyy to Japanese Prime Minister Fumio Kishida, all but pleading with lawmakers to approve the aid. Globally, the delay left many questioning America’s commitment to its allies.

At stake has also been one of Biden’s top foreign policy priorities — halting Russian President Vladimir Putin’s advance in Europe. After engaging in quiet talks with Johnson, the president quickly endorsed Johnson’s plan, paving the way for Democrats to give their rare support to clear the procedural hurdles needed for a final vote.

“We have a responsibility, not as Democrats or Republicans, but as Americans to defend democracy wherever it is at risk,” Jeffries said during the debate.

While aid for Ukraine will likely win a majority in both parties, a significant number of progressive Democrats are expected to vote against the bill aiding Israel as they demand an end to the bombardment of Gaza that has killed thousands of civilians.

At the same time, Donald Trump, the presumptive Republican presidential nominee, has loomed large over the fight, weighing in from afar via social media statements and direct phone calls with lawmakers as he tilts the GOP to a more isolationist stance with his “America First” brand of politics.

Ukraine’s defense once enjoyed robust, bipartisan support in Congress, but as the war enters its third year, a bulk of Republicans oppose further aid. Trump ally Rep. Marjorie Taylor Greene, R-Ga., offered an amendment to zero out the money, but it was rejected.

At one point, Trump’s opposition essentially doomed the bipartisan Senate proposal on border security. This past week, Trump also issued a social media post that questioned why European nations were not giving more money to Ukraine, though he spared Johnson from criticism and said Ukraine’s survival was important.

Still, the ultraconservative House Freedom Caucus has derided the legislation as the “America Last” foreign wars package and urged lawmakers to defy Republican leadership and oppose it because the bills do not include border security measures.

Johnson’s hold on the speaker’s gavel has also grown more tenuous in recent days as three Republicans, led by Greene, supported a “motion to vacate” that can lead to a vote on removing the speaker. Egged on by far-right personalities, she is also being joined by a growing number of lawmakers including Reps. Thomas Massie, R-Ky., who is urging Johnson to voluntarily step aside, and Paul Gosar, R-Ariz.

The package includes several Republican priorities that Democrats endorse, or at least are willing to accept. Those include proposals that allow the U.S. to seize frozen Russian central bank assets to rebuild Ukraine; impose sanctions on Iran, Russia, China and criminal organizations that traffic fentanyl; and legislation to require the China-based owner of the popular video app TikTok to sell its stake within a year or face a ban in the United States.

Still, the all-out push to get the bills through Congress is a reflection not only of politics, but realities on the ground in Ukraine. Top lawmakers on national security committees, who are privy to classified briefings, have grown gravely concerned about the situation in recent weeks. Russia has increasingly used satellite-guided gliding bombs — which allow planes to drop them from a safe distance — to pummel Ukrainian forces beset by a shortage of troops and ammunition.
