WASHINGTON — President Biden on Monday announced a new $2.5 billion military aid package for Kyiv, spending all remaining congressionally approved Ukraine Security Assistance Initiative (USAI) funds before leaving office next month. 

It was part of nearly $6 billion in additional military and budget assistance that Biden’s administration is sending to Kyiv ahead of President-elect Donald Trump’s takeover on Jan. 20.

“At my direction, the United States will continue to work relentlessly to strengthen Ukraine’s position in this war over the remainder of my time in office,” Biden said in a statement.

The US made available $3.4 billion in budget aid to Ukraine, which has been used to help keep the President Volodymyr Zelensky’s government running as Russian forces target critical civilian infrastructures during the war.

The additional assistance marks the final disbursement of funds appropriated under bipartisan legislation that Biden, 82, signed earlier this year as part of a $95 billion foreign aid package that included nearly $61 billion in military and economic funding for Ukraine, $17 billion in military assistance for Israel, $9 billion for Gaza and other war-torn regions and $8.1 billion for Taiwan and other Indo-Pacific allies.

The Ukraine provisions comprised $1.25 billion in weapons from Pentagon stockpiles and allocates the remaining $1.22 billion left of USAI funds to purchase new military equipment for Ukraine.

While the weapons from US stockpiles are likely to make it into Ukrainian hands before Trump takes office, those given through the USAI funds typically take months to years to deliver because they must first be procured.

“It has been a top priority of mine to provide Ukraine with the support it needs to prevail,” Biden said. “Today’s announcement … builds on this effort and will provide Ukraine with both an immediate influx of capabilities that it continues to use to great effect on the battlefield and longer-term supplies of air defense, artillery and other critical weapons systems.”

In total, Congress has given Ukraine roughly $175 billion in both military, economic and humanitarian assistance since Moscow invaded the country on Feb. 23, 2022.

About $61.4 billion of those funds went toward weapons systems and other military aid, according to the Pentagon.

“The Department of Defense is in the process of delivering hundreds of thousands of artillery rounds, thousands of rockets and hundreds of armored vehicles which will strengthen Ukraine’s hand as it heads into the winter,” Biden said.

Yellen said continued economic aid for Ukraine was crucial to allow it to “defend its sovereignty and achieve a just peace by maintaining the critical government services that underpin its brave fight.”

“Ukraine’s success is in America’s core national interest,” she said, noting that the aid is “conditioned on reforms related to strengthening law enforcement, improving transparency and efficiency of government institutions, and bolstering anti-corruption rules and procedures.”

“Stopping Russia’s illegal invasion will help uphold a global democratic, rules-based, order that advances American security and economic interests, and it will send an unmistakable message to autocrats and would-be aggressors around the world that they will face unshakeable resolve. We must not retreat in this effort.”
