It comes on the heels of a renewed push by the White House for additional support for Ukraine. The US Congress, however, is still not close to a deal on a compromise spending package that would help fund the war effort.

“We are out of money – and nearly out of time,” wrote Shalanda Young, the White House budget director, in a letter to Republican and Democratic leaders published on Monday.

She warned that a failure by Congress to approve more military aid to Ukraine before the end of the year would “kneecap” the nation in its fight against Russia and that there was no “magic pot of funding” left to draw from.

On Monday, however, the Republican Speaker of the House of Representatives, Mike Johnson, seemed dismissive of the latest pleas to provide tens of billions of dollars more in funding.

“The Biden Administration has failed to substantively address any of my conference’s legitimate concerns about the lack of a clear strategy in Ukraine, a path to resolving the conflict, or a plan for adequately ensuring accountability for aid provided by American taxpayers,” he wrote on social media.
