Biden reaffirms U.S. commitment to Ukraine, says Russia responsible for crimes against humanity

President Joe Biden on Tuesday in Poland said Russia committed crimes against humanity in its invasion of Ukraine and reaffirmed the United States would continue to support Kyiv,

"Ukraine will never be a victory for Russia," Biden told a crowd in Warsaw, Poland, as part of his trip to war-torn Ukraine nearly one year into Russia's invasion. "Brutality will never grind down the will of the free."

Days after Vice President Kamala Harris said Russia committed crimes against humanity, in his speech, Biden reiterated her remarks and condemned the "extraordinary brutality of Russian forces and mercenaries."

Biden also directly addressed the Russian people.

"I speak once more to the people of Russia," he said. "The United States and the nations of Europe do not seek to seek to control or destroy Russia. The west was not plotting to attack Russia, as [President Vladimir] Putin said today. And millions of Russian citizens only want to live in peace with their neighbors are not the enemy. This war was never a necessity. It’s a tragedy."

His comments come hours after Putin said Russia will suspend its participating in the New START Treaty, which is the last remaining nuclear arms control agreement between Moscow and the U.S.
