Democratic National Committee Chair Jaime Harrison is frustrated, isolated and trapped in a job he long thought he wanted, according to party insiders, a dynamic driven by escalating tensions with the White House over his role.

Key decisions for the committee are made by White House Deputy Chief of Staff Jen O’Malley Dillon, who speaks frequently with other DNC officials but only about three times a month by Zoom with Harrison. The limits of his influence are a source of agitation for Harrison, according to several people who have spoken to him.

At the same time, he’s not flying to meet with donors or visiting DNC headquarters. Instead, since he first took the post a year ago, Harrison has mostly stayed in his home state of South Carolina, according to people familiar with his schedule, as well as people who frequently see him around town. That has been a major point of consternation for the White House.
