Former Defense Secretary Jim Mattis is re-joining the Hoover Institution at Stanford University in May as the Davies Family Distinguished Fellow.
“I believe we have an obligation to pass on the lessons we’ve learned so that future generations can study, learn and become better,” Mattis said in a press release. “Hoover has made this part of its mission, and I look forward to returning.”
Mattis was a fellow at Hoover until he became secretary in January 2017. He left DOD at the end of 2018.
