With war funding for both Ukraine and Israel now seemingly snarled up beyond repair in Congress, on Thursday the Pentagon said that funding delays have forced the US to begin restricting the flow of military assistance to Ukraine, and the Pentagon has only $1 billion left to replenish stocks of weapons that were sent to the country, according to a spokeswoman.

"We have had to meter out our support for Ukraine," Deputy Pentagon spokeswoman Sabrina Singh told reporters. "We're going to continue to roll out packages but they are getting smaller."

Singh urged Congress to break a deadlock and approve the Biden administration's $61.4 billion request for emergency funds for Ukraine's fight against Russia, part of a masive $106 billion package that would include aid for Israel and the US-Mexico border, but which now has virtually no chance of passing.
