President Biden warned on Tuesday that Russia was celebrating American division over providing aid to Ukraine, as President Volodymyr Zelensky hit a wall of resistance from congressional Republicans during a daylong lobbying blitz in Washington.
Speaking from the White House with Mr. Zelensky by his side, Mr. Biden said failing to support Ukraine would be a gift to President Vladimir V. Putin of Russia.
“Putin is banking on the United States failing to deliver for Ukraine,” Mr. Biden said at the White House. “We must, we must, we must prove him wrong.”
Republican leaders in Congress have insisted that any aid for Ukraine be paired with tighter security at the southern border, arguing that the migrant crisis had become a threat to national security.
