The Trump administration has postponed classified briefings about Iran for members of the Senate and the House as lawmakers continue to question the legality of the US’s attacks on Iranian nuclear sites.

The Associated Press news agency, citing multiple informed sources, reported that the Senate briefing has been rescheduled for Thursday so that Defense Secretary Pete Hegseth and Secretary of State Marco Rubio can attend. Speaker Mike Johnson said the House briefing has been pushed back to Friday.

Democrats slammed the delay.

Senate Democratic Leader Chuck Schumer said it is “outrageous” that the administration postponed the briefings.

“There is a legal obligation for the administration to inform Congress about precisely what is happening,” Schumer said. “What are they afraid of? Why won’t they engage Congress in the critical details?”

Congressman Pete Aguilar, chair of the House Democratic caucus, meanwhile, said that legislators “need evidence, we need details and we need to know them now”.
