The Berger Action Fund is a nondescript name for a group with a rather specific purpose: steering the wealth of Hansjörg Wyss, a Swiss billionaire, into the world of American politics and policy.
As a foreign national, Wyss is prohibited from donating to candidates or political committees. But his influence is still broadly felt through millions of dollars routed through a network of nonprofit groups that invest heavily in the Democratic ecosystem. Such groups don't have to disclose the source of their funding — or many details about how they spend it.
