One can pretty easily see the impact of COVID-19 there, even on countries that are not testing and therefore not reporting any cases...
Unfortunately I haven't been able to find that data for the US.
They include "deaths per day" in one of the charts. Early on I found their stats to be consistent with other trusted sources; but I've not confirmed that recently.
For countries that don't test, that number is zero. Quite the useless metric to report.
Much more meaningful would be: "(actual deaths/day) - (avg deaths/day of 2019)"
In the graphs right at the top of the page you can see several locations have more deaths than usual even if you subtract the covid19 ones. These are likely covid19 deaths that haven't been included in the stats, probably due to lack of testing.
According to that page, New York City, where almost 1 in 600 of the total population (not just of the infected) have died, is likely now tracking its stats pretty accurately.

There's some lag in these figures. The CDC will have something eventually.
