The Washington Times reports on the Landmark Legal Foundation’s letter to the IRS regarding reports of unions’ political activity in 2010.

A conservative public-interest law firm has asked the Internal Revenue Service to make sure three large national labor unions comply with tax and disclosure laws in their planned spending of nearly $100 million to save Democrats in the 2010 congressional elections.

The Virginia-based Landmark Legal Foundation sent a letter on Tuesday to Lois G. Lerner, director of the IRS’ tax exempt organizations division, asking that the agency monitor “this unprecedented political activity.”
