Before the voting, the House began a somber but serious debate with an unusual sense of purpose as Republican committee chairs and top Democrats on the panels united to urge swift passage that would ensure the United States supports its allies and remains a leader on the world stage.

“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.

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. Speaker Mike Johnson (R-La.), putting his job on the line, is relying on Democratic support to ensure that the military and humanitarian package is approved and that help flows to the U.S. allies.

There will be a series of votes on three aid bills, for Ukraine, Israel and the Indo-Pacific, as well as a fourth that contains several other foreign policy proposals, including a clampdown on the popular social media platform TikTok.

If the votes are successful, the package will go to the Senate, where passage in the coming days is nearly assured. President Biden has promised to sign it immediately.

“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.”

Passage through the House would clear 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, skeptical of U.S. support for Ukraine, 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 Asia.

“The only thing that has kept terrorists and tyrants at bay is the perception of a strong America, that we would stand strong,” Johnson said this week. “And we will. I think that Congress is going to show that. This is a very important message that we are going to send the world.”

Still, Congress has seen a stream of world leaders visit in recent months, from Ukrainian President Volodymyr Zelensky 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 this week, 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,” the House Democratic leader, New York Rep. Hakeem Jeffries, said during the debate.

Voting on the package is likely to create unusual alliances in the House. 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.

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 Rep. Marjorie Taylor Greene of Georgia, 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 speaker’s office has been working furiously to drum up support for the bill, as well as for Johnson. It arranged a series of press calls in the lead-up to the final votes on the package, first with Jewish leaders, then with Christian groups, to show support for the speaker and the legislation he is bringing to the floor.

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 also 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.
