The House rejected two amendments to a spending bill late Wednesday night that would have cut funds to the Congressional Budget Office (CBO), the nonpartisan office in charge of estimating the budgetary effects of legislation.

The Republican and Democratic leaders of both the House Budget Committee and Ways and Means Committee came out against the bills.

The first amendment, offered by Rep. Scott Perry (R-Pa.), would have slashed the CBO’s funding by 50.4 percent. That figure, Perry said, was to match the discrepancy between the CBO’s predictions for how many people would gain health insurance under ObamaCare, and the number that actually did.

“Who among us works half the time, gets it doubly wrong and gets a paycheck? The CBO,” Perry said.

Defenders of the CBO have noted that the predictions were made before the Supreme Court struck down parts of the law requiring states to accept Medicaid expansion and that few alternative predictions are consistently more accurate.

Members of the Trump administration have regularly derided and denounced the CBO, which has projected that its healthcare laws would lead to millions more uninsured, and disputed claims that its budget plan would balance.

The amendment was defeated by a vote of 314 to 107.

“Too often, predictions made by CBO turn out to be off the mark,” Griffith said.

“This amendment is not the best way to accomplish our goal of obtaining better analysis from the CBO,” she said. Instead, she added, she would hold hearings in the budget committee in the autumn over ways to improve CBO’s models.

That amendment was defeated by a vote of 309 to 106.
