Rep. Debbie Dingell (D-MI) announced Wednesday that she is returning home to Michigan after the death of her 12-day-old great-granddaughter. Dingell shared the news on Facebook and X, saying she would leave Washington to be with her family.   “Today I am returning home to be with my family during an incredibly painful and deeply personal time,” Dingell posted on X. “Our family’s 12-day-old daughter, granddaughter, and great-granddaughter has returned home to God this afternoon. We have been in God’s hands throughout all of this,” she continued. “While I had planned to be present for votes today and tomorrow, my family needs me now,” she said. “In moments like this, there is no greater responsibility than being by the side of those we love, offering comfort, support, and remembrance.”  Dingell, 72, has no biological children but became stepmother to her late husband John Dingell’s four children, making the infant part of her extended family. She succeeded her husband in Congress in 2015. Colleagues shared messages of support on social media. “Sending our deepest condolences to Debbie,” said New York Republican Congressman Mike Lawler on X. “Keeping her granddaughter and the entire Dingell family in our prayers.” “Our deepest sympathies, thoughts, and prayers are with the Dingell family during this difficult time,” The Michigan Democratic Party responded.
