What meeting. There was no scheduled meeting of CHTP officials with FDA. There would be an FDA team responsible for pulling together all the paperwork, writing the FDA letter (be it approval, a CRL, or denial), and getting it signed off by all the powers-to-be and getting it send to CHTP. But that would have been totally internal to the FDA and CHTP would not be of it and would not know where it stands at any given time.
CHTP would have had no knowledge of what was happening at the FDA, no knowledge of who may or may not be at work because of the storm, or even unless the government sent notice if the FDA was closed completely for the day.
