Had House Republicans’ stopgap bill been adopted, it would have cut hundreds of billions of dollars from programs important to millions of Americans, including nutritional aid for poor pregnant mothers, housing subsidies for low-income families, and medical research and environmental protection, among many other federal operations.

Although the House GOP plan would spare the military, veterans’ benefits and immigration enforcement from cuts, many other domestic programs would face immediate 30 percent budget reductions, and some education subsidies and energy aid for poor families would be axed by more than half.

The spending levels for the next fiscal year, which begins Sunday, were supposed to have been set in a deal that McCarthy and President Biden agreed to in exchange for House support to suspend the debt ceiling. But as McCarthy has struggled to win over a handful of conservative lawmakers, he instructed House Republicans to draft bigger and bigger spending cuts that make all full-year funding bills dead on arrival in the Senate.
