Washington (CNN) The Trump administration has abruptly canceled four classified congressional briefings related to the ongoing Iran crisis , in some cases providing little or no explanation for doing so. The State Department called off two briefings that had been scheduled for Wednesday, Senate and House aides confirm to CNN. The staffer told CNN there was no noticeable chill in the planning process for the briefing on embassy security after the State Department shifted the topic. The State Department sent a global warning to all US embassies before the strike occurred, a senior State Department official said and the department spokesperson confirmed, but it was not directed at specific embassies and did not warn of an imminent attack. The State Department did not respond to CNN's request for comment regarding either schedule change.
