The former first lady took several subtle and clear jabs at former President Donald Trump, contrasting his past scandals with Harris' years of accomplishments.

"She understands that most of us will never be afforded the grace of failing forward we will never benefit from the affirmative action of generational wealth," she said.

"If we bankrupt a business or choke in a crisis, we don’t get a second, third, or fourth chance," she added.

Michelle Obama got more direct and noted that Trump "did everything in his power to try to make people fear us."

"His limited and narrow view of the world made him feel threatened by the existence of two hardworking, highly educated, successful people who also happened to be Black," she said.

"Who’s going to tell him that the job he’s currently seeking might just be one of those 'Black jobs?'" Obama asked to a cheering crowd.

"It’s his same old con: doubling down on ugly, misogynistic, racist lies as a substitute for real ideas and solutions that will actually make people’s lives better," she added.

Emhoff sent the crowd into a tizzy after attendees had been lagging in energy.

The first gentleman told a story of his first date with Harris, prompting cheers when describing by an awkward voicemail he sent her.

Michelle Obama reflected on her mother's memory and the values that she instilled in her from an early age.

"Kamala Harris and I built our lives on those same foundational values. Even though our mothers grew up an ocean apart, they shared the same belief in the promise of this country," she said.

Obama continued to tout Harris' skills, experience and temperament during her years of service.

"Kamala Harris is more than ready for this moment," she said. "She is one of the most qualified people ever to seek the office of the presidency."

The crowd at the United Center greeted former first lady Michelle Obama with a standing ovation as she took the stage as the penultimate speaker.

Michelle Obama said until recently she had mourned the "dimming" of hope felt in the country following the recent developments in the country and the loss of her mother.

However, she said she recently felt it spreading again.

"America, hope is making a comeback," she said.
