In his remarks, Biden spoke mostly about the Coronavirus threat, saying it 'doesn't care if you're a Democrat or a Republican," as he urged Americans to help each other in this time of national crisis.
"We are all in this together," Biden said.
Sanders also took time on Tuesday to speak about the Coronavirus in his own web chat, but did not mention the Tuesday primary results, or whether he would stay in the Democratic race.
While Sanders certainly has the money and organization to stay in the Democratic race through June, he has now lost 19 of the last 24 states since winning in New Hampshire and then Nevada.
Biden's victory was never in doubt on Tuesday, as he first swept to a very convincing win in Florida, beating Sanders 62-23 percent.
In the heavy Democratic precincts of South Florida, Sanders struggled to even get to 20 percent of the vote in Palm Beach, Broward, and Miami-Dade counties, three spots which are crucial for any Democrat in November.
Biden swept all 67 counties in Florida - just as he had done a week earlier when he won every county in Michigan, Mississippi, and Missouri.
That sweep was almost repeated in Illinois on Tuesday until Sanders held his ground in Champaign County, narrowly holding off Biden in the home of the University of Illinois.
