A House Ways and Means Committee investigation into tech millionaire Neville Roy Singham's funding activities has resulted in subpoenas to three connected nonprofits, prompting the organizations to formally challenge the congressional action. The nonprofits argue the subpoenas constitute a violation of free speech protections and represent a revival of Cold War-era investigative tactics.

The committee's probe examines Singham's alleged network of approximately $591 million in funding directed toward far-left nonprofits and causes. Lawmakers are investigating claims of connections between Singham and Chinese Communist Party interests. The nonprofits counter that the investigation unfairly targets their political activities, framing it as a contemporary witch hunt similar to McCarthyism.
