Pete Buttigieg says an anonymous caller filed a false report to Child Protective Services that forced him to spend a night apart from his four-year-old twins and Michigan State Police say they consider the allegation politically motivated.Investigators report the caller claimed Mr. Buttigieg confessed to violent crimes years earlier during a chance encounter in Alabama, a claim Mr. Buttigieg denies and says he has never visited the town alleged.Child Protective Services arranged forensic interviews for the children and instructed Mr. Buttigieg not to be alone with them while the inquiry proceeded, and police say they will not refer charges after finding no evidence.Officials and advocates warn that false emergency reports, often called swatting, are rising in political contexts, risk public safety, waste law enforcement resources and have targeted same-sex parents and public figures.
