Minyon Moore Helped Kamala Harris Rise. Now She’s Leading the D.N.C.

When Vice President Kamala Harris takes the convention stage to formally accept the Democratic nomination on Thursday, it will mark the culmination of decades of public and behind-the-scenes work to make the party more reflective of its multiracial base.

Off the convention stage, the moment is particularly meaningful for a group of Black women in Democratic politics who have long championed Ms. Harris’s political rise. And in a serendipitous intertwining of events, one of them is running the whole show.

Those who know Minyon Moore, the veteran Democratic strategist and chair of this year’s Democratic National Convention, say she is accustomed to operating behind the scenes. She helped lobby President Biden to select Ms. Harris to be his running mate in 2020. She later left a job in the private sector to help coordinate the effort to support Ketanji Brown Jackson’s Supreme Court nomination.

“You could probably take a bag of rocks and throw it in the air at the D.N.C. convention and they’re going to fall on somebody who’s going to tell you a story about the time that Minyon Moore quietly helped them, quietly pushed them, quietly accelerated them to a place where they now are now yielding influence in a very powerful way,” Jotaka Eaddy, a veteran Democratic organizer, said.

Ms. Moore’s role overseeing the convention has required her to depart from the private meetings and side phone calls that have been features of her professional career. It may also test the coalition-building skills she has spent nearly four decades honing. Thousands of demonstrators are expected in Chicago this week to protest the convention and Democrats’ handling of the humanitarian crisis in Gaza caused by the war between Israel and Hamas.

Some of those tensions are on display within the event itself. A group of delegates representing the Uncommitted movement, which has protested the Biden administration’s Israel policy, have joined some of the demonstrations and are hosting separate programming.
