Launched in February 2010, American Action Network is a conservative 501(c)(4) group chaired by Norm Coleman, a Republican former senator from Minnesota. The group reported spending more than $26 million in the 2010 congressional elections, targeting dozens of Democratic House and Senate candidates. Because it is a 501(c)(4), it is not required to release the names of its donors. American Action shares office space with Crossroads GPS/American Crossroads, one of the largest outside spending networks, which has ties to GOP operative Karl Rove. As a nonprofit organization, it does not disclose the donors to its outside spending efforts.
