Hillary Clinton Makes History as Democratic Nominee

Hillary Clinton clinched the Democratic presidential nomination Tuesday evening after securing enough delegates during the roll call vote on the floor of the convention, making history as the first female nominee of any major party.

Prior to clinching the historic vote, speeches for both candidates, including calls for unity, were met with rollicking applause from the audience.

The roll call comes as party leaders fight for unity in the aftermath of a bruising primary campaign between Clinton and Sanders.

Tulsi Gabbard, a Sanders delegate from Hawaii, and a vocal supporter of his throughout the race, spoke before the start of the roll call vote about the potential legacy of Sanders' campaign, calling it a "movement of love."

Some Sanders' supporters raised their fists in solidarity while Gabbard spoke. A woman waved a sign that read, "Hey DNC save the party-nominate Sanders."

"I am truly honored to nominate Bernie Sanders for president of the United States," Gabbard concluded.

Gabbard was the first of several Sanders supporters to testify on his behalf at the start of the roll call. Sanders could be seen smiling warmly while listening to the speakers.

Sanders supporters in the crowd could be seen weeping during the testimony.

Rep. John Lewis, from Georgia, a prominent Clinton backer and civil rights activist, said "we are not going back, we are going forward" in endorsing his candidate, and called Clinton "one of the most qualified candidates to ever run for president."

Competing chants of "Bern-ie" and "Hill-a-ry" broke out as states announced their votes. Larry Sanders, brother of Bernie Sanders, spoke emotionally of his brother and their family while Democrats Abroad announced their tally.

Bernie Sanders appeared to well up while listening to his brother speak.

He grew emotional a second time while the state of Vermont announced its delegate total. He reached for the microphone, and endorsed Clinton a final time, saying that all votes be moved to her total.

Competing cheers for both candidates broke out on the floor.

The opening night of the Democratic National Convention on Monday was a rowdy one, underscored by disagreements between supporters of the two candidates.

Delegates and supporters of Sanders jeered at several speakers including perceived progressive allies like Elizabeth Warren and even Sanders himself for voicing their support for Clinton.

Outside of the convention floor yesterday, protesters voiced anger with the DNC and with Clinton on a number of issues, including the environment, legalized drugs, and the Trans-Pacific Partnership (TPP).

Some observers viewed today's roll call as the final opportunity for Sanders supporters to voice their displeasure with Clinton. Both Clinton and Sanders were up for the nomination at the DNC, which was largely considered to be a symbolic gesture for Sanders supporters. Each candidates' supporters will have 20 minutes of floor time to make speeches in support of their candidates.
