In a Democratic primary marked by the demonization of corporate cash and the influence of big money in politics, Joe Biden made his first major appearance after he kicked off his campaign at a private high-dollar fundraiser rather than at a public event or rally open to all supporters.

While the former vice president was spotted Thursday at a pizzeria and talked to reporters at a train station in Wilmington, Del., Biden’s first major appearance as a 2020 candidate was at the home of Comcast executive David L. Cohen in Philadelphia for a fundraiser that evening.
