Black women leaders and their allies are swiftly mobilizing and fundraising around Vice President Kamala Harris‘s presidential campaign after President Joe Biden stepped down from the Democratic ticket.

In one notable example, a black women’s advocacy group raised $1.5 million within three hours in support of Harris on Sunday evening. Win With Black Women announced that more than 44,000 black women joined an impromptu Zoom call to strategize on how best to support Harris. The off-the-record call quickly reached capacity, with organizer Jotaka Eaddy having to increase capacity.
