Except from visiting the @POTUS on January 11 2012, Darden has been to the White House twice.
On May 1 2012 he visited Nancy Sutley:
She is a central figure within Environmental Policy. From other links it seems that she is connected to both the AGW climate agenda
and to the Clintons.
Then, as recently as November 6 2015, Darden visited Gabriele Fisher who was an intern at the National Security and International Affairs. Hmm.
Among others these people were attending this meeting according to a comment by “Uchoads”:
According to the same website Darden also visited the White House on 6th Nov 2015. He went to two meetings apparently organised by Gabriele Fisher, a “National Security and International Affairs Intern” from the “White House Office of Science and Technology Policy”
Also in attendance (among 80 others) were:
Jeff Baran – Commissioner of the U.S. Nuclear Regulatory Commission.
Steve Corneli – Senior Vice President for Policy and Strategy, NRG Energy.
Theodore Garrish – who provides strategic compliance advice on matters relating to the export of nuclear technology.
Janet Gorn – Senior Foreign Affairs Officer at U.S. Department of State.
Mary Alice Hayward – Bureau of International Security and Nonproliferation
Arthur Samberg – Boardmember of Tri Alpha Energy (aneutronic fusion)
Kristine Svinicki – Commissioner of the U.S. Nuclear Regulatory Commission
Kevan Weaver – Terrapower (Bill Gates’ travelling wave reactor)
Jay Wileman – CEO, GE Hitachi Nuclear Energy
Also interesting to note is that JT Vaughn visited Erin Szulman at the office of Science an Technology Policy on June 16th 2015. She was formerly at the Department of Energy.
It gets even more interesting realizing that this meeting took place about the date when the first Penon report was received by IH (three months into the test).
All in all, this points to the White House being seriously involved since probably 2011 (when the first MW reactor was sold to a military customer in Bologna). I would say it strengthens my hypothesis of Darden being part of a high level scheme to control IP and LENR roll out.
