First Lady Michelle Obama gave a rousing and emotional appeal to Democrats on the opening night of their nominating convention by laying out the choice in November in stark terms: Who do you want to mold the next generation?

Obama outlined a different set of Clinton’s characteristics, emphasizing her tenacity, her steadiness and her work ethic.

“Hillary Clinton has never quit anything in her life,” Obama said.

“When you have the nuclear codes at your fingertips and the military at your command, you can’t have a thin skin or a tendency to lash out,” Obama said.

She said she and President Barack Obama have taught daughters Sasha and Malia to “Ignore those who question their father’s citizenship or faith,” something Trump has done.

“Our motto is: When they go low we go high,” Obama said.
