Please substantiate that claim.
But when doing that, please apply the following rule. The only cuts that count are the ones that take effect no later than the 2026 budget. Alleged cuts in future years that pretend that legislation passed in 2025 can somehow force future Congresses to have the courage to cut spending that the Congress in 2025 doesn't have the courage to cut now don't count.
I maintain that if you apply this restriction, you will find that the BBB legislates net spending increases, not decreases. It includes an immediate increase of $150 billion in annual spending for the military. That takes effect immediately. Does it have cuts that take effect immediately that add up to more than that? I highly doubt it. But I'm open to being proven wrong.
And no, I am not counting tax cuts as spending increases. Leave the tax parts of the bill out and just focus on what it legislates for spending.
