But the coronavirus pandemic has reduced the nominating celebration to a minimal footprint in Milwaukee — with major programming and production details still in flux just days before it is set to begin.Former first lady Michelle Obama will be the keynote speaker of the night, after remaining mostly on the sidelines throughout the 2020 political season.Sen. Bernie Sanders, the former rival of presumptive Democratic candidate Joe Biden, and former Ohio Gov. John Kasich, a Republican candidate for president in 2016, will also speak.Here’s Monday’s lineup of speakers:Sen. Amy Klobuchar, D-Minn.Sen. Catherine Cortez Masto, D-Nev.New York Gov.
