They've passed the EGO Act, which bans the long-time practice of legislators sitting for taxpayer-funded oil portraits. People were becoming increasingly irritated by it, as it no longer serves any purpose in this age of high-quality digital photography and seems therefore a waste of half a million dollars per year. Granted, the way government goes through money, a half-million's sort of a pittance - but it's a tiny step in the right direction.
Senator Bill Cassidy (R-LA), has been fighting to liberate thousands of dollars in tax revenue from servicing his fellow politicians’ egos since 2013, when he first introduced the Eliminating Government-Funded Oil Painting Act (the “Ego” act for short—and yes, that was intentional). The bill failed to pass in 2013, although its proponents attempted compromise by proposing a spending cap of $20,000. After this setback, the bill’s spendthrift spirit made its way into the 2014 budget as a rider on the annual Congressional spending bill. Now, the prohibition is permanent.
One hopes that this sort of fiscal restraint might become habitual, although it's more than likely just a one-off.
