Ukrainian First Lady Olena Zelenska met with Secretary of State Antony Blinken in the United States on Monday, ahead of her address to Congress at the U.S. Capitol later this week.

Zelenska’s visit to the U.S. comes as Ukraine continues to defend itself against a Russian invasion that started on Feb. 24.

The two leaders discussed Ukraine’s ongoing war with Russia and humanitarian efforts to help Ukrainian refugees displaced by the struggle.

"He reiterated that the United States will continue to provide assistance to help Ukraine respond to the significant economic and humanitarian challenges it faces, including supporting the first lady’s mental health initiative for citizens affected by the war," Price added.

The U.S. has already sent billions of dollars worth of supplies and military equipment to Ukraine to assist in the struggle, but Ukrainian President Volodymyr Zelenskyy says his country needs additional armaments if his country holds any hope of defeating Russia.  

"The secretary reiterated that the United States remains dedicated to helping the people of Ukraine recover and rebuild from the devastation inflicted on them by [Russian] President Putin's unjust war," he added.

President Zelenskyy virtually addressed Congress in March, when he told members his country was experiencing a mass civilian tragedy "every day" because of Russian attacks on Ukraine.

"Remember Sept. 11, a terrible day in 2001 when evil tried to turn your cities, independent territories, into battlefields. When innocent people were attacked from the air," Zelenskyy said on March 16. "Our country is experiencing the same every day, right now, at this moment."
