RePower Fund (sometimes written Re:Power), formerly known as Wellstone Action Fund, is the 501(c)(3) charitable arm of far-left political training organization RePower (formerly Wellstone Action). Formed in Minnesota in 2003, the fund helps finance the parent organization’s left-wing political leadership programs. 
U.S. Senator Paul Wellstone (D-MN), a staunch liberal; his wife, Sheila; and their daughter died in a plane crash on October 25, 2002.  Established in 2003 as the Wellstone Action and the Wellstone Action Fund—now known, respectively, as RePower and the RePower Fund—were created to continue the far-left legacies of the Wellstones. 
Both organizations were renamed in 2018 after the late senator’s two sons, Mark and David Wellstone, were voted off the board of directors.  Their ousting reportedly stemmed from voicing concerns about overspending in areas of the organization’s budget, and what its priorities should be in the future. 
In 2016, the RePower Fund reported $2.3 million in total earnings, with $1.8 million in coming from donors. 
Approximately 85 percent of the money donated to the group, came from three far-left groups: the Proteus Fund, Foundation to Promote Open Society, and the Ford Foundation. Broken down by group, the Proteus Fund gave $300,000; Foundation to Promote Open Society, which is run by billionaire liberal donor George Soros, gave $537,000; and the Ford Foundation contributed $700,000.   
The primary activity of the RePower Fund is financially supporting RePower’s left-wing leadership trainings.  Its top training program, Camp Wellstone, is entirely funded by the RePower Fund.  In addition, the fund transfers some of its income directly to RePower.  In 2015, the RePower Fund transferred more than 30 percent of its revenue to RePower—exceeding $1 million. 
The group is led by a board of directors, which consists of seven members.  Sara Beth Mueller currently serves as the interim executive director of RePower and RePower Fund.  Prior to her employment at the organization, Mueller was the Director of Communications at Planned Parenthood Minnesota, North Dakota, South Dakota. 
Although officially separate groups, the RePower Fund exists to support RePower, its parent organization.
