President 
Bush on Aug. 17 announced plans to nominate Michael W. Wynne to become the new Secretary of the Air Force. Wynne, a West Point graduate, has served as the principal undersecretary of defense for acquisition, technology, and logistics. Bush did not say when he would officially forward Wynne’s nomination to Congress. If confirmed, he would succeed James Roche, who left the post earlier this year. Bush earlier had appointed Preston “Pete” Geren, a former Texas Congressman, to serve as Acting SECAF, and he will continue in that post until Wynne is installed in office.
The Office of the Undersecretary of Defense for Personnel and Readiness revised the Defense Department’s COVID-19 guidelines. The new rules clarify what’s meant by being “up to date” on vaccinations and when personnel must wear masks in vehicles, among other changes.
