In a highly unusual move, national security adviser John Bolton convened a meeting at CIA headquarters last week with the Trump administration's top intelligence, diplomatic and military advisers to discuss Iran, according to six current U.S. officials.

The meeting was held at 7 a.m. on Monday, April 29, and included CIA Director Gina Haspel, Acting Defense Secretary Patrick Shanahan, Chairman of the Joint Chiefs of Staff Gen. Joe Dunford, Secretary of State Mike Pompeo, and Director of National Intelligence Dan Coats, five of the officials said.

National security meetings are typically held in the White House Situation Room. The six current officials, as well as multiple former officials, said it is extremely rare for senior White House officials or Cabinet members to attend a meeting at CIA headquarters.

The officials said the discussion was not about the intelligence that led to the decision in the following days to send a carrier strike group and bomber task force to the Middle East, but did not describe what the meeting covered.
