A week after unveiling a stunning projection for the number of people who would die from coronavirus in the US -- 100,000 to 240,000 -- White House officials have yet to fully explain how they arrived at those numbers. Some administration officials are now saying the number could be lower than they originally warned -- but it comes as there are continued questions about how the administration got to the high number. The final number could end up being higher or lower than the dramatic estimates released one week ago in a briefing by the White House Coronavirus Task Force, according to federal health officials and researchers who are creating models to forecast the outbreak.
