President Donald Trump has appointed Adam Telle as the acting U.S. Army Secretary, an unorthodox move that bypasses the service's second-most senior civilian official, Undersecretary Michael Obadal. Telle, who was confirmed by the Senate last August to oversee the Army’s civil works portfolio, also has a background as a Senate GOP staffer. This appointment follows the resignation of former Army Secretary Dan Driscoll earlier this week. Reports suggest Driscoll's departure was influenced by tensions with Pentagon chief Pete Hegseth, who praised Telle's appointment. The change marks the latest in a series of departures from the Pentagon's civilian and uniformed ranks.
