US President Donald Trump's senior national security officials gathered on Friday at Camp David for closed-door discussions on the Iran war and the Saudi-Houthi conflict in Yemen, Axios reported. Citing three American officials, Axios said Vice President JD Vance presided over the undisclosed meeting, which ran for hours. Secretary of State Marco Rubio, Defence Secretary Pete Hegseth, special envoy Steve Witkoff, CIA chief John Ratcliffe and Joint Chiefs Chairman General Dan Caine also took part.
