WASHINGTON (AP) — Ukrainian President Volodymyr Zelenskyy has told leaders in Congress that with U.S. aid his country can win the war with Russia. But Zelenskyy arrived Tuesday on Capitol Hill to a darker mood than when he swooped in last winter for a hero’s welcome. He also met on Tuesday with President Joe Biden, who made his own plea to Congress to provide billions in aid. Biden’s request for a $110 billion U.S. aid package for Ukraine, Israel and other national security needs is at serious risk of collapse in Congress. Republicans are insisting on strict U.S.-Mexico border security changes in exchange for any Ukraine aid. Senate Majority Leader Chuck Schumer called Tuesday’s meeting with Zelenskyy “powerful” but outlined no new path for a deal.
