The presumptive Democratic presidential nominees and their spouses will gather in Pittsburgh on Sunday before taking off on a bus tour. The bus is expected to travel through the state on its way to Chicago, where the Democratic National Convention gets underway on Monday. The time and location of the kickoff event are not yet announced. Vice President Harris and her husband — Doug Emhoff — and Minnesota Governor Walz and his wife — Gwen Walz — will be together for the first time since the ticket was decided.
