The federal government is conducting a criminal investigation related to Gov. Gavin Newsom's international travel and its funding, according to subpoenas reviewed by The Standard. The subpoenas " which were issued in early September and requested testimony and communications with the governor, among others " seek six years of records involving the California State Protocol Foundation, a nonprofit that has paid for Newsom's overseas travel, as well as communications with a circle of his current and former aides, advisers, and associates. Those aides include Rebecca Prowda, who oversees Newsom's overseas travel as his chief protocol officer and is the wife of San Francisco Mayor Daniel Lurie.
