Biden says he thinks the Democratic convention will 'have to move into August'

"I doubt whether the Democratic Convention is going to be able to be held in mid-July or early July. I think it's gonna have to move into August," the former vice president told Jimmy Fallon on "The Tonight Show" Wednesday night. "We just have to be prepared for the alternative and the alternative, we don't know what it's going to be unless we have a better sense of whether this curve is going to move down or up."

As the number of confirmed coronavirus cases continues to rise across the United States, there have been unexpected changes to the election process, including postponed primaries and a virtual halt of all in-person campaigning. During an interview on MSNBC Tuesday, Biden said it was "hard to envision" Democrats gathering in an arena and the convention taking place as planned.

CNN previously reported that Democrats are considering a range of contingency plans for the convention, including shortening the in-person portion or going entirely digital.

Biden also criticized President Donald Trump's response to coronavirus and the lack of testing kits. He said the President just started to "grasp the reality" of the potential death toll the pandemic will take on the country.

"There's a sense of urgency that doesn't seemed -- only until yesterday at his press conference, the President start to grasp the reality of what he's facing in terms of the number of potential deaths, the number of people who are going to contract the virus," he told Fallon. "We got a lot, a lot to do, and we're not getting it done."

During a White House press briefing Tuesday, the President warned of a "painful" two weeks ahead as he extended social distancing guidelines to April 30, casting a grim outlook that even if the guidelines are followed, it could still mean more than 100,000 and up to 240,000 Americans die from the virus.
