WATCH: Vice President Harris Meets With President Zelenskyy at White House

Vice President Kamala Harris and President Joe Biden each met separately Thursday with Ukrainian President Volodymyr Zelenskyy at the White House. 

In her remarks following their meeting with Ukrainian President Volodymyr Zelenskyy, Vice President Harris reiterated her support for Ukraine, telling reporters, "I’ve been proud to stand with Ukraine, I’ll continue to stand with Ukraine, and I will work to ensure Ukraine prevails in this war."

Framing Ukraine's fight against Russia as one reflective of American values, Vice President Harris reiterated the country's support of its ally. "The American people know well the meaning of freedom, of independence, and the importance of the rule of law," the Vice President told the press. "These ideals are central to who we are as Americans and some of the most important moments in our history have come when we stood up to aggressors like Putin."

"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. ... The U.S. can not and should not isolate ourselves from the rest of the world. Isolation is not insulation," the Vice President added.

President Zelenskyy spoke after Vice President Harris and told reporters why he had once again traveled to Washington despite not being welcome by Congressional Republicans. "We have to end this war, we need a just peace," President Zelenskyy said. "We must protect our people: Ukrainian families, Ukrainian children, and everyone from Putin's evil. We are grateful to America for supporting Ukraine all along."
