Elizabeth Warren had more than a little pressure on her to deliver a unifying message during the opening night of the Democratic National Convention in Philadelphia, where angry Bernie Sanders supporters were disrupting what is supposed to be Hillary Clinton's big party. Even for a progressive politician who's as beloved as Warren (many had hoped she would run or at least be Hillary Clinton's running mate), it was going to be a tough situation.

Warren also had to follow First Lady Michelle Obama, which wasn't easy. However, at the DNC, there's one move you probably can't go wrong with: bashing Donald Trump. Warren proved once again that she's very, very good at it.

"We are here tonight because America faces a choice, the choice of a new president. On one side is a man who inherited a fortune from his father and kept it going by cheating people, by skipping out on debts. A man who has never sacrificed anything for anyone. A man who cares only for himself, every minute of every day," Warren said of Trump. "... Trump's entire campaign is just one more late night Trump infomercial. Hand over your money, your job, your children's future and the great Trump hot air machine will reveal all the answers. And for one, low, low price, he'll even throw in a goofy hat."

Warren's speech didn't go over without interruption, though. After praising Sanders for "remind[ing] us what Democrats fight for every day," she turned to Hillary.

"On the other side is one of the smartest toughest most tenacious people on this planet, a woman who fights for children, for women, for healthcare, for human rights. A woman who fights for all of us and who is strong enough to win those fights. Hillary Clinton. We're here today because our choice is Hillary Clinton. I'm with Hillary. I'm with Hillary."

That's when pro-Sanders supporters began chanting, "We trusted you. We trusted you." Warren continued:

"You know, for me, this choice is personal. It's about who we are as people, it's about what kind of a country we want to be. I grew up in Oklahoma. My daddy ended up as a maintenance man and my mom worked a minimum wage job at Sears. My three brothers served in the military. The oldest was career, 288 combat missions in Vietnam. The second worked construction. The third started his own business. Me? I got married at 19, graduated from a commuter college in Texas that cost $50 a semester. The way I see it, I'm a janitor's daughter who became a public school teacher, a professor, and a United States senator. America is truly a country of opportunity, truly. I am deeply grateful to that America. I believe in that America."

The vehemently anti-Trump Massachusetts senator had to speak to a party that's still torn by a divisive primary. Meanwhile, Sanders supporters were outside of the DNC protesting, and were booing any mention of Hillary Clinton inside—even when it was coming from Sanders himself. The DNC email leak that ultimately ousted DNC chairwoman Debbie Wasserman Schultz had the Berners even more amped up.

The DNC continues at Philadelphia's Wells Fargo Center this week. You can watch the Complex News live stream from the convention, here.
