The Pentagon’s top two technology experts have submitted their resignations.

Mike Griffin, who became the Defense Department’s first undersecretary of research and engineering in early 2018, and his deputy Lisa Porter have both submitted their resignations, a defense official confirmed to Defense News. The two will be exiting the building July 10.

In a letter to R&E staff, Griffin and Porter wrote that “a private-sector opportunity has presented itself to us, offering an opportunity we have decided to pursue together.”

“It has been a pleasure leading this great team over the past few years. We greatly appreciate your hard work, diligence, integrity, and devotion to technical excellence and technical truth in furtherance of the R&E mission,” the duo wrote. “We wish you all the very best.”
