Berger Action Fund

The Berger Action Fund is a 501(c)(4) nonprofit liberal advocacy group based in Washington, D.C. It is associated with the Wyss Foundation, which is the funding vehicle of Swiss billionaire Hansjörg Wyss. The Berger Action Fund has been a major donor to the Sixteen Thirty Fund, which is a hub of undisclosed political spending on the American Left. The New York Times wrote that the Berger Action Fund is part of Wyss' "sophisticated political operation to advance progressive policy initiatives and the Democrats who support them." The Berger Action Fund has donated nearly $500 million to left-leaning nonprofits.
