Many of us, including Leo, have asked "Why now?"
My theory is that "they" now fear a more enlightened Congress. Notwithstanding the public's pre-election outcry and attempted lawsuits, the 2009 Congress arguably felt safe hiding behind the first CRS memo.
The issue is now even stronger in the public's mind. Further, a substantial amount of information, research and patently bogus BC's have shed light on this national fraud. My intuition says "they" fear an avalanche.
Law suits are piling up and Secretaries of 57 States need official propaganda to dismiss them.
