At least three people have withdrawn from consideration to lead Sen. Amy Klobuchars nascent 2020 presidential campaign and done so in part because of the Minnesota Democrats history of mistreating her staff, HuffPost has learned.
earlier article shows this has a ten year history:
Minnesota Sen. Amy Klobuchars mistreatment of her office staff began more than a decade ago and eventually caused such concerns that in 2015, then-Senate Minority Leader Harry Reid (D-Nev.) spoke to her privately and told her to change her behavior, multiple sources have confirmed to HuffPost.
