just found this on Russia Today site:

This year’s Bilderberg meeting has drawn protestors not just from Spain, but from all over Europe and the world. They are not objecting wholesale to the meeting taking place – what bothers them is the veil of secrecy that has been drawn over everything that is linked to the elite club.

Despite that accusation, US Treasury Secretary Timothy Geithner has previously attended the Bilderberg meeting, and is rumored to be at this year’s event too.
