The aides said the speakers were Foreign Secretary Mike Pompeo, Defense Secretary Patrick Shanahan, Joint Chiefs of Staff General Joseph Dunford and an unnamed intelligence representative.
A congressional aide said last week that a Senate hearing was set for Tuesday, but the final details of the House meeting were yet to be finalized.
