Ukrainian President Volodymyr Zelenskyy will arrive on Capitol Hill to a darker mood than when he swooped in last winter for a hero’s welcome, as the Russian invasion is grinding into a third year and U.S. funding hangs in balance.

Zelenskyy’s visit Tuesday comes as President Joe Biden’s request for an additional $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 that Democrats decry as draconian in exchange for the overseas aid.

“It is maddening,” said Sen. Chris Coons, D-Del., a close ally of Biden, of the stalemate. “A very bad message to the world, to the Ukrainian people.”
