Excerpt:

The Logan Act

This super-powerful world organization runs out of an 18m2 (194 square feet) office, staffed by one person. It uses one one telephone line and a single fax number. There is no web page or name plate on the door. The independent press have never been allowed access and no statements have ever been released on the attendees' conclusions. No Bilderberg meeting agenda has ever been made public. "It is the epitome of low-profile dark ops, a shadow government hidden in a doorway." According to critics and close observers, it's agenda is to weaken all world leadership but their own. It is also, according to a U.S. law called the Logan Act, ^[15] illegal:

"A US law, called the Logan Act, states explicitly that it is against the law for federal officials to attend secret meetings with private citizens to develop public policies. Although Bilderberg 2005 was missing one of its luminaries, US State Department official John Bolton who was testifying before the Senate Foreign Relations Committee, the American government was well represented in Rottach-Egern by Alan Hubbard, assistant to the president for economic policy and director of the National Economic Council; William Luti, deputy under secretary of defense; James Wolfensohn, outgoing president of the World Bank and Paul Wolfowitz, deputy secretary of state, an ideologue of the Iraq War and incoming president of the World Bank. By attending Bilderberg 2005 meeting, these people are breaking federal laws of the United States.”^[16]
