The U.S. House of Representatives on Thursday approved legislation providing aid to Ukraine and imposing new sanctions on Russia, underscoring growing Republican willingness to break with party leadership and push back against President Donald Trump.

Lawmakers voted 226-195 in favor of the Ukraine Support Act, which reached the floor after months of delay. A small group of Republicans joined Democrats earlier to sign a discharge petition, forcing the measure to a vote.

Eighteen Republicans and one independent who typically votes with them ultimately sided with Democrats to pass the bill, highlighting a widening fracture within a party that has largely aligned with Trump’s foreign policy positions.

Passage came a day after a smaller group of House Republicans joined Democrats to approve a resolution that would require the withdrawal of troops from hostilities with Iran unless Congress declares war or authorizes the use of military force.

Olha Stefanishyna, Ukraine’s ambassador to the United States, said in a post on X that the decision was “an important step forward” and “reflects continued bipartisan support for Ukraine.”
