The Democratic National Convention kicked off in Philadelphia Monday afternoon with some of the party’s biggest names trying to rally support around candidate and former Secretary of State Hillary Clinton. Massachusetts Sen. Elizabeth Warren, who endorsed Clinton in June and has been sparring with Republican nominee Donald Trump for months, is helping to lead the effort to unify the party. Her remarks Monday night will be available by live stream here as well as via Twitter and major news networks like C-SPAN.

First Lady Michelle Obama and Vermont Sen. Bernie Sanders will also take the stage Monday. Congressman Joe Kennedy III will introduce Warren, who is expected to speak some time after 9:30 p.m. EDT.

Monday night’s theme is focused on putting families first and underscoring Clinton’s long political background. Warren has been hailed as one of the Democratic Party’s most progressive voices and while she was late to endorse Clinton, she has since made appearances with the candidate and was reportedly on the shortlist of potential vice presidential running mates.

Trump and Warren have regularly traded comments on social media for the past few months. The New York businessman has called Warren "Pocahontas," mocking her Native American heritage.

“She’s got about as much Indian blood as I have,” Trump said in March while speaking with the New York Times. “Her whole life was based on fraud. She got into Harvard and all that because she said she was a minority.”

Warren has been rallying voters to cast their ballots in November for Clinton. She told the National Council of La Raza, a group that advocates for Latinos, last week that Trump was “a man born with cash in his fist and hate in his heart.”

Focusing her remarks before the largely Latino audience, Warren said that Trump’s accusations against Mexican-American judge Gonzalo Curiel showed the candidate’s true colors. Warren called Trump a “bigot.”

“We believe that we must make Hillary Clinton the next president of the United States,” Warren said. “And make Tim Kaine the next vice president. Not can, not should — we must.”
