The U.S. House of Representatives has approved a major aid package for Ukraine and new sanctions targeting Russia, with a group of Republican lawmakers breaking ranks with party leadership to support the measure.

The Ukraine Support Act passed on Thursday by a vote of 226-195 after 18 Republicans joined Democrats in backing the legislation. The vote marks the latest instance of divisions within the Republican Party over foreign policy and President Donald Trump’s approach to international conflicts.

The bill would provide more than $1 billion in security and reconstruction assistance for Ukraine, while authorizing an additional $8 billion in financing and loans to support the country’s defense efforts against Russia.

Despite clearing the House, the legislation faces significant hurdles. It must still pass the Senate and secure President Trump’s signature before becoming law, making its future uncertain.

The vote was made possible after Republican supporters joined Democrats in signing a discharge petition, a procedural move that allowed lawmakers to bypass House leadership and force consideration of the bill on the floor.

The House action comes amid growing signs of bipartisan concern over the administration’s foreign policy decisions. Earlier this week, a small group of Republicans joined Democrats in supporting a resolution aimed at preventing further U.S. military involvement in Iran. Although largely symbolic, the measure reflected unease among some lawmakers about the expanding conflict.

The White House dismissed the Iran resolution as an unconstitutional attempt to limit presidential authority. Nevertheless, its passage increased pressure on the administration to outline a clearer strategy for ending the conflict.

Meanwhile, the Trump administration has abandoned plans to establish an “anti-weaponization” fund after facing criticism from both Democrats and some Republicans. The proposal had become a source of contention on Capitol Hill, with several Republican lawmakers threatening to oppose key immigration legislation unless the plan was withdrawn.

The developments underscore growing tensions within Congress as lawmakers debate U.S. foreign policy, military engagements, and government spending priorities.
