Former Sen. Orrin Hatch, the Utah Republican who served 42 years in Congress, has died at the age of 88, his foundation announced Saturday.

Hatch, the longest-serving senator in Utah’s history, died at 5:30 p.m. local time Saturday surrounded by family in Salt Lake City. The foundation, which the senator launched in early 2019 as he retired from his seat, declined to provide a cause of death. The group’s press release also said that funeral arrangements would be forthcoming.
