The Democratic National Convention will be postponed until August due to coronavirus concerns, planners said Thursday, in a historic and stunning change to the presidential election calendar.

The convention committee said the event will be held the week of Aug. 17, in Milwaukee, Wis. It was originally slated for July 13-16.

“In our current climate of uncertainty, we believe the smartest approach is to take additional time to monitor how this situation unfolds so we can best position our party for a safe and successful convention. During this critical time, when the scope and scale of the pandemic and its impact remain unknown, we will continue to monitor the situation and follow the advice of health care professionals and emergency responders,” Joe Solmonese, CEO of the Democratic National Convention Committee, said in a statement.

“I have always believed that American innovation and ingenuity shine brightest during our darkest days, and for that reason, I’m confident our convention planning team and our partners will find a way to deliver a convention in Milwaukee this summer that places our Democratic nominee on the path to victory in November.”

The announcement comes just hours after former Vice President Joe Biden -- the likely nominee -- said he expected such a delay.

“I doubt whether the Democratic Convention is going to be able to be held in mid-July, early July. I think it's going to have to move into August,” Biden said Wednesday night in an interview with Jimmy Fallon on NBC’s "The Tonight Show."

Biden pointed out that “even then, the Republican and Democratic Convention, we're going to have to ... we just have to be prepared for the alternative and the alternative.”

The former vice president hinted that how long the worst effects of the pandemic last would determine convention planning.
