Russia-Ukraine war: Biden warns of 'Christmas gift' to Putin

US President Joe Biden and Ukrainian President Volodymyr Zelenskyy presented a united front against Russian aggression in a high-stakes meeting at the White House. Biden warned that Russian President Vladimir Putin is "banking on the United States failing to deliver for Ukraine" and called on Congress to pass supplemental funding for Ukraine before the holiday recess. Both leaders faced criticism from Republicans over military aid to Ukraine. Russia's intensified military campaign in Ukraine and the impasse in Congress over aid pose challenges for US foreign policy.
