In a last effort before the Trump administration takes office, the Biden White House plans to announce an additional $1.25 billion in military assistance to Ukraine.

The package includes munitions for the National Advanced Surface-to-Air Missile Systems (NASAMS) and the HAWK air defense system, as well as Stinger missiles, 155 mm and 105 mm artillery rounds, according to the Associated Press. The announcement is expected Monday.

This follows Biden’s recent $988 million aid package, which he said ensures Ukraine “has the tools it needs to prevail in its fight against Russian aggression,” Fox News reports.

“This administration has made its choice. And so has a bipartisan coalition in Congress. The next administration must make its own choice,” Defense Secretary Lloyd Austin said at the Ronald Reagan Presidential Library. “From this podium, I am confident that President Reagan would have stood on the side of Ukraine, American security, and human freedom.”

The Biden administration has prioritized delivering aid to Ukraine before Trump assumes office in January.

During the campaign, President-elect Trump and Vice President-elect JD Vance criticized the Biden administration’s support for Ukraine following Russia’s 2022 invasion. Trump pledged to end the war before taking office but provided no specifics. Vance suggested that Ukraine cede occupied territories and establish a demilitarized zone, a proposal Ukrainian President Volodymyr Zelenskyy strongly rejected.

Recently, Trump met with Zelenskyy during a ceremony in Paris commemorating the reopening of Notre Dame Cathedral after its 2019 fire.

This $1.25 billion aid package is the administration’s 22nd under the Ukraine Security Assistance Initiative. Earlier this month, House Speaker Mike Johnson rejected the administration’s request for an additional $24 billion in Ukraine funding.

“It is not the place of Joe Biden to make that decision now,” Johnson stated. “We have a newly elected president, and we’re going to wait and take the new commander in chief’s direction on all that. So, I don’t expect any Ukraine funding to come up now.”
