As President Donald Trump privately mulled joining Israel’s campaign against Iran this month, one member of his Cabinet sent what he viewed as an audacious attempt to steer him in the opposite direction.

At 5:30 a.m. on June 10, Director of National Intelligence Tulsi Gabbard tweeted a cryptic, three-minute video warning that “political elite and warmongers” are “carelessly fomenting fear and tensions between nuclear powers” — and that the world is “on the brink of nuclear annihilation.”

Trump saw the unauthorized video and became incensed, complaining to associates at the White House that she had spoken out of turn, according to three people familiar with the episode — two of them inside the administration and all granted anonymity to describe sensitive dynamics.

Her post came a few days after Israel hawks met with Trump at the White House to lobby him to support Israel’s attacks on Iran. In the eyes of Trump and some close to him, Gabbard was warning him not to greenlight Israel attacking Iran. Trump even expressed his disapproval to her personally, the three people said.
