White House homeland security adviser Tom Bossert is leaving the Trump administration, “another departure during what has been a chaotic few months of personnel changes,” the Washington Post reports.

“Bossert, a favorite of Chief of Staff John F. Kelly, is leaving one day after national security adviser John Bolton began the job. Bossert, an ally of former national security adviser H.R. McMaster, was believed to be on shaky footing in the Bolton era and he resigned two days after Michael Anton, the National Security Council spokesman, also quit.”
