A secretive meeting of more than 100 of the world's most powerful people just took place in a Washington, D.C. hotel behind closed doors and under tight security — while few reporters even took note.

Bilderberg Meetings attendees — including the director of the CIA, the secretary-general of NATO, European prime ministers, CEOs of pharmaceutical, energy and tech companies (including Pfizer CEO Albert Bourla) — gathered June 2-5 to discuss global issues under an anonymity agreement.

"The participants take part as individuals rather than in any official capacity, and hence are not bound by the conventions of their office or by pre-agreed positions," the group's website states.

On the agenda of the invitation-only summit were topics including "Disruption of the Global Financial System," "Disinformation," "Energy Security and Sustainability," "Post Pandemic Health" and "Fragmentation of Democratic Societies."

As an element of its secrecy, the annual conference invokes the "Chatham House Rule." In meetings held under this rule, "participants are free to use the information received, but neither the identity nor the affiliation of the speaker(s) nor of any other participant may be revealed."
