During the presidential transition process, Donald Trump announced that Tom Bossert would serve in a newly created position: assistant to the president for homeland security and counterterrorism. In the months that followed, Bossert maintained a fairly high profile on a number of issues, including making multiple Sunday-show appearances on behalf of the White House.
In fact, Bossert was on ABC's "This Week" just two days ago, defending the president's plans for the U.S./Mexico border and discussing possible plans for responding to Syria's alleged chemical weapons attack. He made no mention of a change in career plans.
And yet, Bossert is now the latest departure from Team Trump.
President Donald Trump's homeland security adviser, Tom Bossert, has resigned, the White House said Tuesday, making him the latest in a long line of senior officials to leave the administration.
On Monday night, Bossert was socializing with current and former U.S. Intelligence officials at a conference at the Cloisters resort in Sea Island, Georgia. A source close to him told NBC News that the adviser was not aware there was any intention at the White House to seek his resignation and had no plans to quit.
"New team," the source said, without further explanation.
Given the circumstances, that's probably a reference to John Bolton officially starting yesterday as the White House national security adviser, following a stint as a Fox News personality.
Of course, the timing could be better. As Trump adopts an aggressive new border policy, and prepares a response to Syria, it seems like an odd time for the president to accept the resignation of his top adviser on "homeland security and counterterrorism."
Nevertheless, Bossert's departure comes a day and a half after National Security Council spokesperson Michael Anton also announced his departure, in a move that's also widely believed to be tied to Bolton's arrival in the White House.
