The CDC has a webpage that lists "Table 1. Deaths involving coronavirus disease 2019 (COVID-19) and pneumonia reported to NCHS by week ending date, United States. Week ending 2/1/2020 to 4/4/2020.*" with column "All COVID-19 Deaths (U07.1)" showing 3307 deaths.
But on the CDC page "Cases in the US", it says the total deaths for just COVID-19 is 12,064.
Why does the CDC website say there are ~9,000 more deaths when not tracking pneumonia?
