Tulsi Gabbard’s congressional testimony came a day after a top deputy, Joe Kent, resigned in protest over the war.

Director of National Intelligence Tulsi Gabbard declined to say if Iran’s nuclear program presented an “imminent threat,” deflecting questions from lawmakers about whether U.S. intelligence backed up White House statements on the rationale for starting the war.

Gabbard’s congressional testimony Wednesday at an annual hearing on worldwide threats came a day after a top deputy, Joe Kent, resigned in protest over the Iran war, saying that the Tehran regime posed no imminent threat and the joint U.S.-Israeli air campaign was unnecessary.

Kent and Gabbard, both military veterans, had found political common ground over their opposition to foreign military interventions and “regime change” wars like Iraq and Afghanistan. Gabbard has not publicly endorsed the decision to go to war, staying mostly silent on the U.S.-Israeli air campaign that began on Feb. 28.
