The Senate overwhelmingly approved a $40 billion infusion of military and economic aid for Ukraine and its allies on Thursday as both parties rallied behind America’s latest, and quite possibly not last, financial salvo against Russia’s invasion. The 86-11 vote gave final congressional approval to the package, three weeks after President Joe Biden requested a smaller $33 billion version and after a lone Republican opponent delayed Senate passage for a week. Every Democrat and all but 11 Republicans — many of them supporters of former President Donald Trump’s isolationist agenda — backed the measure. Biden’s quick signature was certain as Russia’s attack, which has mauled Ukraine’s forces and cities, slogs into a fourth month with no obvious end ahead. That means more casualties and destruction in Ukraine, which has relied heavily on U.S. and Western assistance for its survival, especially advanced arms, with requests for more aid potentially looming.
