President Biden called on Republicans to quickly elect a new House speaker and to change what he called the “poisonous atmosphere in Washington.” Biden said he’s worried congressional gridlock threatens to derail White House efforts to win new funding for U.S. aid to Ukraine — though Biden said his administration has enough funds in reserve to continue sending arms shipments for now, and suggested he has a path around Congress if it fails to approve more funding.

President Joe Biden: “We can support Ukraine in the next tranche that we need. And there is another means by which we may be able to find funding for that. But I’m not going to get into that now.”

On Wednesday, the Biden administration said it supplied Ukraine with thousands of assault rifles and more than a million rounds of ammunition seized in the Persian Gulf by the U.S. Navy. The Justice Department says the arms were being sent by Iran’s Revolutionary Guard to Houthi rebels in Yemen in violation of a U.N. arms embargo.
