A major personnel change is coming to the Trump White House as Press Secretary Karoline Leavitt announces she will step down at the end of the month.

White House correspondent Jon Decker breaks down Leavitt’s departure, her rise from a White House intern to the youngest press secretary in history, and President Donald Trump’s announcement that she will remain one of his top outside advisers as Republicans prepare for the midterm elections.

Then, President Trump declares that the United States has “total control” of the Strait of Hormuz amid the ongoing war with Iran. Jon examines the reality on the ground, dramatically reduced shipping traffic through the critical waterway, the impact on global oil supplies, and the threat that continued disruptions could drive energy and shipping costs even higher.

New details are also emerging about President Trump’s extraordinary secret transfer from Air Force One following a potential Iranian assassination threat in Turkey. Jon reveals which members of Trump’s inner circle accompanied the president aboard a catering truck and military aircraft—and which senior administration officials remained behind.

Finally, the Justice Department has reportedly convened a rare special grand jury in Washington, D.C., potentially opening the door to investigations involving some of the nation’s most controversial cases.

It’s all on this edition of the White House Briefing Room with Jon Decker.
