Kennedy signed Executive Order 11110 (which granted the Treasury authority to directly issue money in the form of silver certificates) five months before his assassination. He also gave this speech seven months before his death.
Thank you for the link.
It is easy to forget how good a speaker he was and how
he moved us who were still relatively young then.
The speech of his that most rings in my mind these days is the one where he had the chart and he pointed out how reducing taxes would stimulate the economy.
