The Biden administration on Thursday asked Congress to provide more than $13 billion in emergency defense aid to Ukraine and an additional $8 billion for humanitarian support through the end of the year, another massive infusion of cash as the Russian invasion wears on and Ukraine pushes a counteroffensive against the Kremlin’s deeply entrenched forces.

The package includes $12 billion to replenish the U.S. federal disaster funds at home after a deadly climate season of heat and storms, and funds to bolster the enforcement at the Southern border with Mexico, including money to curb the flow of deadly fentanyl. All told, it’s a $40 billion package.

While the last such request from the White House for Ukraine funding was easily approved in 2022, there’s a different dynamic this time.
