PHILADELPHIA — In a speech that concluded with a standing ovation from the crowd, first lady Michelle Obama made the case for Hillary Clinton for president by reminding her fellow Democrats of what kind of leader will be best for their own children.

"Today, I wake up every morning in a house that was built by slaves, and I watch my daughters, two beautiful intelligent black young women playing with their dogs on the White House lawn," Obama said at the Democratic National Convention. "In this election, and every election, it is about who will have the power to shape our children for the next four or eight years of their lives. ...

"There is only one person who I trust with that responsibility … and that is our friend, Hillary Clinton," she said as the crowd roared in applause. Obama's voice often quivered with emotion as she delivered her speech.

Clinton is expected to formally accept the Democratic nomination on Thursday, just a week after business mogul Donald Trump became the Republican nominee.

Obama said she believed Trump is unfit to hold the highest office in the land because of his temper.

"When you have the nuclear codes at your fingertips and the military in your hands, you can't make snap decisions," she said, adding the presidency "can't be boiled down to 140 characters."

Obama is no stranger to the Democratic National Convention's spotlight, having delivered speeches in both the 2008 and 2012 conventions.
