"But that's one of the reasons we're not at the high end of that plane as opposed to the low end of the plane," the president continued.
When Trump was pressed on his changing estimate, Trump admitted: "I used to say 65,000, and now I say 80 or 90, and it goes up, and it goes up quickly."
"But it will still be, no matter how you look at it, right at the lower end of the plane if we did the shutdown," he said.
Earlier Sunday, Dr. Deborah Birx, a White House labor official, offered Trump's various figures on the United States death toll from the virus.
"Our projections have always been lost between 100-240,000 American lives, and it is with full limitation and we are learning from each other how to social distance," Birx told Chris Wallace on "Fox News Sunday."
Trump's remarks on Sunday night come after he projected between 50,000 to 60,000 US deaths from the coronavirus in a White House press release less than two weeks ago.
"Now we're going to 50 – I hear, or 60,000 people. One is too many. I always say that," he said at the time. "One is too many, but we are going towards 50 or 60,000 people. It's at the lowest – as you know, the lower (end of projections) should be 100,000 people."
In March, Trump acknowledged that deaths in the United States from coronavirus could reach 100,000 or more, adding that if the deaths stay at or below 100,000, "we've all done a very good job."
This claim came after the president was asked for comments by the nation's top infection expert, Dr. Anthony Fauci, on CNN's "State of the Union" in March that 100,000 Americans or more could die from the virus based on models.
By Sunday, the number of Americans infected with the virus topped 1.1 million with more than 67,000 dead, according to data from Johns Hopkins University. And as some states release home stay orders, scientists are researching a higher coronavirus death rate this summer than previously expected.
