Harris discussed the controversial "Project 2025" conservative policy proposals contending that would mean "Donald Trump with no guardrails."

"He would use the immense powers of the presidency of the United States not to improve your life, not to strengthen our national security, but to serve the only client he has ever had: himself," she said.

"Its sum total is to pull our country back to the past," Harris said of "Project 2025. "But America, we are not going back."

After proclaiming, "America, we are not going back," the crowd erupted into chants of "we're not going back."

The chants got so loud that at first, you couldn't hear Harris over the speakers.

Harris called the election "one of the most important in the life of our nation" as she pivoted to talking about Trump.

She called him an "unserious man" who if put back in the White House would have "extremely serious" consequences.

"Consider not only the chaos and calamity when he was in office, but also the gravity of what has happened since he lost the last election," she said, going on to discuss the insurrection and fraud verdict.

"I know there are people of various political views watching tonight, and I want you to know, I promise to be a president for all Americans," she said. "You can always trust me to put country above party and self, to hold sacred America's fundamental principles, from the rule of law to free and fair elections, to the peaceful transfer of power. "

"I will be a president who unites us around our highest aspirations, a president who lead us and listens, who is realistic, practical and has common sense and always fights for the American people from the courthouse to the White House," she continued. "That has been my life's work."
