WATCH: Tulsi Gabbard makes opening statement in worldwide threats hearing

Tulsi Gabbard, director of national intelligence, reiterated Thursday that "Iran's strategic position has been significantly degraded" as a result of U.S.-Israeli attacks. Top U.S. intelligence officials were testifying Thursday before the House Select Committee on Intelligence at an open hearing on worldwide threats. It's the second day of hearings on Capitol Hill focused on the intelligence community's release of its annual assessment of threats to national security. On Wednesday, Democratic senators pressed Gabbard on the reasoning behind the U.S.-Israel attacks on Iran and whether she offered any guidance to President Donald Trump, among other topics. National Counterterrorism Center Director Joe Kent resigned Tuesday over the war. Kent, a former Green Beret and CIA official known for his past ties to right-wing extremists, posted his resignation letter on X, writing directly to Trump that Iran "posed no imminent threat" to the U.S. and he could not "in good conscience" support the war.  Kent told Tucker Carlson in a podcast interview Wednesday that he and “other key decision makers” were “not allowed” to share their opinions with the president.
