U.S. Accuses Irvine Woman of Watching Taiwan President's Son for Beijing

U.S. prosecutors allege Wanying Zhang, 34, of Irvine, watched Taiwanese President William Lai Ching-te's son Lai Ting-yu and his family on orders from Chinese officials. She is charged as an unregistered foreign agent — working for Beijing without telling U.S. authorities. Officials say relatives beyond official protection can be pressure points, a core counterintelligence concern.
