The author I could not recall the name is Antony C. Sutton. His notable works and interviews include:
● Wall Street and the Bolshevik Revolution
● Wall Street and the Rise of Hitler
● An Introduction to the Order of Skull & Bones
The press briefing referred to was the US State Department. The spokesman was Ned Price and the reporter was Matt Lee. There are two links to the videos. The C-SPAN video shows only Price. The RT video also shows Lee.
