President Joe Biden and senior administration officials announced $5.9 billion in new financial and security assistance for Ukraine as the commander-in-chief enters his final weeks in office.

Biden unveiled $2.5 billion on Monday in “security assistance” that will provide the nation with “an immediate influx of capabilities” as well as “longer-term supplies of air defense, artillery, and other critical weapons systems” as the war against Russia approaches a full three years.

“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.

That funding came on the same day that Treasury Secretary Janet Yellen revealed another $3.4 billion in “direct budget support” to bankroll operations for the national government of Ukraine.

“Our direct budget support to Ukraine arrives at a critical time as Russia intensifies its attacks on Ukrainian civilians and critical infrastructure,” Yellen commented. “Economic assistance from the United States and our allies is crucial for Ukraine’s ability to defend its sovereignty and achieve a just peace by maintaining the critical government services that underpin its brave fight.”

Those funds from the Treasury Department marked the last disbursement of the financial aid greenlit under the Ukraine Security Supplemental Appropriations Act passed earlier this year.

Congress has so far approved some $175 billion for Ukraine as they fend off the invasion from Russia, according to one analysis from the Council of Foreign Relations. Most of that financial assistance has been sent to the government of Ukraine for weapons or budgetary support.
