Amid the chaos of the shutdown fight, Republicans snuck in a passage to gut funding for the IRS. And Democrats didn’t catch it.

Over $20 billion meant to strengthen the Internal Revenue Service’s long-term enforcement efforts remains frozen and inaccessible as a result of the legislation President Joe Biden signed Saturday.
