Deficit hawks slammed the budget agreement reached Wednesday between Senate Republican and Democratic leaders, calling it a “betrayal” and the “definition of irresponsibility.”

The deal announced by Senate Majority Leader Mitch McConnell, R-Ky., and Minority Leader Charles Schumer, D-N.Y., would undo caps on defense and domestic spending set by the 2011 Budget Control Act, adding between $300 billion and $400 billion to federal spending over the next two years. Over the next decade, the deal likely would add about $1.5 trillion to the federal debt, according to the Committee for a Responsible Federal Budget.
