KYIV, UKRAINE, MAY 20

Ukrainian President Volodymyr Zelenskyy thanked the United States for the $40 billion aid package, which got final congressional approval on Thursday.

"This is a demonstration of strong leadership and a necessary contribution to our common defense of freedom," Zelenskyy said in his nightly video address to the nation.

He also thanked the European Union for its support.

"And for our partners this is not just an expense or a gift. This is their contribution to security," Zelenskyy said. "For defending Ukraine also defends them from new wars and crises that Russia could provoke if it is successful in the war against Ukraine. Therefore, we must together ensure that Russia's aggression against our state has no success, not militarily, economically or any other."

Zelenskyy said Ukraine's monthly budget deficit is $5 billion "and so to survive in the war for freedom, we need quick and sufficient financial support."

The US has announced a shipment of $100 million in military equipment to Ukraine, separate from what will be coming from the $40 billion approved by Congress. The latest package includes 18 more howitzers as well as anti-artillery radar systems, both of which the US has provided to Ukraine already since Russia invaded Ukraine on February 24.
