Kamala Harris did not speak on election night at Howard University, her alma mater and a historically black university in Washington DC.

After losing the first two battleground states announced, Harris did not appear before a group of on-campus revelers that had started to dwindle as the night wore on.

The Democratic presidential nominee graduated from Howard in 1986 with a bachelor's degree in political science and economics, and maintained close ties with the school.

Howard's president, Ben Vinson III, said that it was the first time in modern history that a college campus has hosted a presidential election watch party.

Mr Vinson said the university was already "incredibly proud" that the first woman of colour to serve as vice-president was among its alumni. "We are also honoured that she has chosen Howard as the place to potentially make history again."

But on Tuesday night, the gathering at Howard became increasingly subdued and around midnight, a senior member of the campaign told the dwindling crowd that Harris would not be appearing tonight.

Two swing states North Carolina and Georgia, had been called for Trump on the big screen mounted outdoors on campus.

Nabila Mangum, 31, decked out in the bright pink of AKA - the sorority she shares with Harris - planned to celebrate election night at Howard. “I was very motivated and excited,” she said.

She felt the mood change in real time, a sudden deflation in the crowd around her.

“The energy went down,” she said. “But, we’re not finished. It’s not over until it’s done."

Harris supporters gathered outside the school earlier Tuesday before the watch party began, but they went eerily silent as they saw North Carolina called for Trump.

“I know there are a lot of worries with the numbers right now," said Howard student Jordan Newsom, soon after the state was projected as a win for Trump.

Mr Newsom said his fellow supporters were doing their best to keep the mood up. “The best we can do is unite and keep the faith amongst ourselves.”

Among the revelers was Cheryl Taylor, the Howard alum who tapped Harris as a freshman to join Alpha Kappa Alpha, the country’s first black sorority, which was founded at Howard in 1908.

Members of AKA and other black sororities form a tight-knit national network that helped boost Harris's presidential bids this year and in 2019.

Even at the age of 19, Ms Taylor told the BBC, Harris stood out as a leader.

"She was amazing. Beautiful, smart, a good person," she said.

Ms Taylor was moved by Harris's decision to hold a watch party at Howard, saying it was a recognition of the school's importance in her journey and the place that showed her the power of "black excellence".

And she shrugged off attacks aimed at Harris's racial identity, including from Donald Trump, who questioned her blackness.

"We don’t question that here," she said.

Waiting with her friends to get in was first-time voter and first-year student Kendall Claytor, who described Harris as a role model.

"As a black woman, I really look up to her," she said.

"You know, knowing that she came from the same place, like she slept in the same dorms that I slept in, she went to the same school, same classes and she’s able to make it this far. I think speaks volumes to us as students."

William Ward, 65, was playing music from the back of his bicycle for the crowd.

"I'm going to be 66 in December. I want to see history. I've seen the Obamas go in, which is history. And now I'm going to see a female go in."

A Destiny's Child song was momentarily drowned out by cheers as screens showed Harris up in early returns from battleground states of Michigan and Pennsylvania.

"I know there's been a lot of work on the ground, and it's so good to see it pay off," said Harris supporter Danielle Sydnor.
