Republicans unilaterally passed a $1.5 trillion tax cut in 2017\u2014zero Democratic votes\u2014and nonpartisan Congressional budget analysts confirmed it added roughly $1.9 trillion to deficits over ten years even accounting for economic growth effects. The deficit grew sharply in the immediate aftermath. That is a straightforward, documented causal link between Republican-authored legislation and deficit expansion.

The evidence instead shows multiple contributing factors, including spending legislation both parties supported.

The vast majority of contracts were completed successfully, undermining the suggestion of fraudulent diversion of funds. One contract with significant cost overruns was actually **cancelled**, the opposite of what a protected slush fund arrangement would produce.
