The White House has asked Congress to approve $37.7 billion in additional aid for Ukraine amid Russia’s invasion, a request that comes ahead of both a government funding deadline and the expected flipping of the House to Republican control.

The Biden administration is requesting that Congress authorize $21.7 billion in defense aid to continue providing equipment to Ukraine and to replenish Department of Defense stocks. It is also asking for $14.5 billion for direct budget support to Ukraine, critical wartime investments and security assistance as well as to strengthen global food security and provide humanitarian assistance.

Additionally, $626 million would go to providing nuclear security support for Ukraine and to modernizing the Strategic Petroleum Reserve to reduce domestic energy costs and ensure sustainable access to energy resources. And $900 million would go to help with health care and support services to Ukrainians.

The new funding would be “to ensure that Ukraine has the funding, weapons, and support it needs to defend itself,” an administration official told reporters when previewing the request on Tuesday.

It would be on top of the nearly $19 billion the U.S. has provided in military assistance to Ukraine since Russia’s full-scale invasion in February.
