The most dangerous man in Washington
But Mulvaney has other plans.
During his six years in Congress, he voted against raising the debt limit four times. One might hope he was merely posturing, since he was able to cast such votes with the knowledge that his colleagues would ultimately pass the bills.
Unfortunately, as OMB director, Mulvaney has continued to be breathtakingly irresponsible with the creditworthiness of the United States.
In May, he publicly contradicted Mnuchin by arguing that a debt-ceiling increase should be coupled with divisive spending cuts, which would inevitably complicate an already politically fraught process.
And on Sunday, he told CNN's Jake Tapper that Congress must not pass any legislation -- not even a debt-ceiling hike -- until the notoriously impossible Obamacare repeal is done. President Trump echoed this thinking on Twitter as well.
So long as Mulvaney still has the president's ear, we're all living dangerously.
