Biden's national security advisor says the US is 'working around the clock to deliver our own weapons' to Ukraine

• Biden's national security advisor Jake Sullivan told "Meet The Press" that the US is sending Ukraine weapons as fast as possible.
• Other NATO countries have also sent Ukraine weapons to fend off Russian troops.

National security advisor Jake Sullivan on Sunday said the United States is shipping off weapons to Ukraine to help Ukrainian soldiers fend off Russian troops.

"We are doing everything we can as the United States, working around the clock to deliver our own weapons," Sullivan said in an interview on NBC's "Meet the Press."

"Weapons are arriving every day, including today," Sullivan said. "And this week, along with Chairman Milley, I spent two hours on the phone with the chief of the Ukrainian Armed Forces and President [Volodymyr] Zelenskyy's top aide. And we went through every weapon system that Ukraine is seeking, in priority order."

"And we have developed plans to deliver those as rapidly as possible," Sullivan continued. "Some have been delivered, others are in the process of being delivered. And we will continue to work aggressively to get Ukraine what it needs to strengthen its hand on the battlefield, and to strengthen its hand at the bargaining table."

Zelenskyy has for weeks asked NATO and Western countries for more support in the fight against Russia. He's asked NATO to impose a no-fly zone over Ukraine in an effort to deter Russian missiles and airstrikes, which the international alliance has rebuffed.

Early in March, Putin warned that any country that tries to impose a no-fly zone will be considered "participants in a military conflict, and it doesn't matter members of which organizations they are."

Ukraine won against Russia in the battle for Kyiv, Sullivan said, partly because of US support.

"But we are not resting until we have given them everything that they need to be able to succeed in their aims," he added.

The war, which began on February 24, has forced millions of Ukrainians to flee their homeland. So far, more than 4.5 million Ukrainians have escaped since the beginning of the invasion, according to data from the United Nations Refugee Agency. In the first week alone, more than 1 million Ukrainians left.

"Our policy is unequivocal that we will do whatever we can to help Ukraine succeed," Sullivan said on "Meet the Press. "And it will be Ukraine. President Zelenskyy and the democratically elected government of Ukraine that determines what that success constitutes. Which means that we need to keep giving them weapons so that they can make progress on the battlefield."
