This is an email from John Brockman to Jeffrey Epstein dated February 6, 2017. Brockman recounts the recent, sudden death of his acquaintance Katinka's brother, provides an update on his own brother Philip's prostate cancer and new treatment, and shares an anecdote about representing the Biosphere 'cult' in the 90s, noting Steve Bannon's role as its former CEO. Brockman concludes by suggesting he is available to meet that afternoon or the next morning.
