At Howard University, where Vice President Kamala Harris is expected to deliver remarks at 4 p.m., the mood is somber and the crowd small.

In sharp contrast to the thousands who gathered Tuesday night, just several hundred are present ahead of the speech Wednesday.

Campaign staffers have been spotted, bleary eyed, hugging and catching up. Some have been in tears, the shock visible on their faces.
