Child welfare experts who reviewed the documents at The Post’s request said they illuminate a flawed process made worse by poor judgment and a lack of communication between agencies in two states. Pete Buttigieg, Chasten Buttigieg, and their children Penelope and Gus attend the annual Easter Egg Roll at the White House in 2023. Nine days after Indiana’s initial call, a Michigan child welfare worker learned from Indiana police that the possible source of the allegation was a “mentally unstable woman in Indiana.” Buttigieg told authorities his family has received “many threats,” including death threats, since he and husband Chasten adopted their twins in 2021. “They are in touch with Michigan authorities, seeking answers and accountability for what happened.”
