That's not my understanding. What I read is that CRs automatically grow spending by an automatic percentage. There was a bill to change that but it either didn't pass or wasn't voted on.
Again. What I read said CRs are always increases and didn't differentiate this one. The only time spending was cut was when Cruz forced the same issue in Obama's early years and they had to go into Sequestor mode.
Much of this is happening because of the CRs they keep passing. I can't comment on Gaetz personally. I don't know his motivations. I do know that the same things were said about Cruz a decade ago. Turned out he was doing the right thing then. So I don't trust the narrative now that is used against those on the Right.
A CR usually holds spending levels in place. However, they can also make funding conditional on budget cuts like what McCarthy pitched a few weeks ago until Gaetz and his crew killed it.
Also, the sequestration was negotiated as part of a debt ceiling deal. Similar but not identical issue as this. And Cruz didn't do the same thing. He did not try to take out his leader, and he had a policy agenda behind his actions. Gaetz does not.
