Watchdog groups asked federal officials Tuesday to crack down on lawmakers who use certain fundraising accounts to finance their golf outings and steak lunches.

Leadership political action committees are meant to help Congress members raise money for their colleagues — thus helping them climb leadership ranks. Because those accounts aren’t subject to the same spending restrictions as the ones candidates use for their own campaigns, they are prone to eyebrow-raising spending activity, or “used as slush funds to subsidize officeholders’ lifestyles,” the Campaign Legal Center and Issue One wrote in a petition to the FEC.

Some of the most egregious spending could be curbed if the FEC would clarify that the prohibition on the use of campaign donations for personal expenses also applies to Leadership PACs, the groups said in a letter to the FEC.

The letter was signed by a bipartisan group of retired House members, Rod Chandler, R-Wash., Larry LaRocco, D-Idaho, Peter Smith, R-Vt., Claudine Schneider, R-R.I., and John Tanner, D-Tenn.
