​​President Biden said Thursday the U.S. will surge nearly $8 billion in new military aid to Ukraine, including long-range missiles. Biden made the announcement ahead of a meeting at the White House with Ukrainian President Volodymyr Zelensky. Biden reportedly did not grant Ukraine permission to fire U.S.-made weapons deep into Russian territory. Zelensky also met separately Thursday with Vice President Kamala Harris, who pledged her “unwavering” support to Ukraine after the talks.

Vice President Kamala Harris: “History has shown us if we allow aggressors like Putin to take land with impunity, they keep going. And Putin could set his sights on Poland, the Baltic states and other NATO allies. Putin started this war, and he could end it tomorrow, if he simply withdrew his troops from Ukraine’s sovereign territory.”

On Wednesday, Russian President Vladimir Putin threatened to use nuclear weapons to respond to Ukraine’s attacks on Russian territory if they were supported by a nuclear-armed nation.
