Briefing on Iran strikes leaves senators divided as Trump threatens new row

Partisan splits on display as president accuses Democrats of leaking draft Pentagon report on bombings' impact

Republican and Democratic senators have offered starkly contrasting interpretations of Donald Trump's bombing of Iranian nuclear facilities after a delayed behind-closed-doors intelligence briefing that the White House had earlier postponed amid accusations of leaks.

Thursday's session with senior national security officials came after the White House moved back its briefing, originally scheduled for Tuesday, fueling Democratic complaints that Trump was stonewalling Congress over military action the president authorized without congressional approval.
