In 2017, Neville Roy Singham married Jodie Evans, a former Democratic political adviser and the co-founder of Code Pink. Since 2017, about a quarter of Code Pink’s donations — more than $1.4 million — have come from two groups linked to Mr. Singham, nonprofit records show. Ms. Evans, 68, was once a Democratic insider who managed the 1992 presidential campaign of the California governor Jerry Brown. After the 2001 terrorist attacks, she reinvented herself as an activist. She became known for pink peace-sign earrings and sit-ins that ended with her arrest. She helped form Code Pink to protest the looming war in Iraq. The group became notorious for disrupting Capitol Hill hearings. Ms. Evans has organized around progressive causes like climate change, gender and racism. Until a few years ago, she readily criticized China’s authoritarian government.
