"Error" implies this was a mistake and not just the most shameless example yet of a kind of double counting that happens very often in DC.
There have been countless Rosie projections for budgets in Washington, sure. Mostly along the lines of projecting particularly and not altogether realistic economic growth to artificially increased Revenue, particularly when coupled with tax cuts that will supposedly stimulate the economy. This however is entirely on a new plane where it is absolute complete double Counting. It is the mathematical equivalent of saying two plus two equals 6 buy double counting the first two. It's unprecedented and it's grotesque dishonesty and disdain for the American public in their ability to see what's going on
lol double counting is not unprecedented. only usually it's just hundreds of billions of dollars.
