Republicans talk often about using the "power of the purse" to rein in a lawless Obama administration. If they mean it, they ought to use their year-end spending bill to stop a textbook case of outrageous executive overreach.

This scandal comes courtesy of the Justice Department, which for 16 months has engaged in a scheme to undermine Congress’s spending authority by independently transferring dollars to President Obama’s political allies. The department is in the process of funneling more than half-a-billion dollars to liberal activist groups, at least some of which will actively support Democrats in the coming election.

It works likes this: The Justice Department prosecutes cases against supposed corporate bad actors. Those companies agree to settlements that include financial penalties. Then Justice mandates that at least some of that penalty money be paid in the form of "donations" to nonprofits that supposedly aid consumers and bolster neighborhoods.

The Justice Department maintains a list of government-approved nonprofit beneficiaries. And surprise, surprise: Many of them are liberal activist groups. The National Council of La Raza. The National Urban League. The National Community Reinvestment Coalition. NeighborWorks America (which awards grants to left-leaning community organization groups, and has been compared with Acorn).
