Q: "It took 3 months from your initial warnings...for the federal government to...require the production of millions more n95 masks...What was the consequence of this 3-month delay? Were lives endangered?"
DR. BRIGHT: "Lives were endangered, and I believe lives were lost."
Note that Dr. Bright didn't confirm the exact time frame in that answer, but did not dispute it either. So, is it true that it took 3 months from the time that Dr. Bright warned about the insufficient production (or stockpiles?) until the Federal government took official action to have production increased?
