Confirmation the tweet is not accurate.
In the US average auto deaths are about 3,300 per day.
12,000,000 a year?
No, can’t be.
About one hundred vehicle accident deaths a day, times 365 days, is 36,500 deaths a year.
About one hundred twenty opioid overdose deaths a day, times 365 days, is about 43,680 deaths a year.
From memory, there were approximately 70,000 opioid overdose deaths in 2017.
POTUS has used these figures more than once in his speeches, the first two more recently, to give context / perspective, to the number of COVID 19 deaths to date.
The numbers are close.
