Debt ceiling negotiations stall as Biden cancels trip and Republicans hold firm.

President Biden and congressional leaders failed to reach a deal to raise the nation's debt limit at a crucial meeting on Tuesday. The talks hit a roadblock before the principals arrived at the White House, with Speaker Kevin McCarthy reiterating his demand to implement stricter work requirements for the Supplemental Nutrition Assistance Program (SNAP), an idea that has run into stiff Democratic resistance. The impasse sets the stage for a dramatic two-to-three weeks of brinkmanship before the Treasury Department finally exhausts its ability to pay the nation's fiscal obligations on June 1.
