Or debrief meeting

It should be debriefING meeting/call, during which a person or group of people are "debriefed" - updated on all the details of something that has occurred.

Спасибо большое)

Да не за что. Кстати, можно и без слов meeting и call: The president and his entire cabinet were present at the debriefing. (=in a meeting or on the phone)
