Taking the center stage of American politics for the first time after becoming the presumptive vice-presidential nominee of the Democratic party, Indian-origin Senator Kamala Harris remembered her mother Shyamala Gopalan, saying it was she who taught her not to sit and complain about things during the time of problem but do something to improve it.

Making her first appearance along with Biden in Wilmington in Delaware, Harris said her mother had a great role in her life.

And my mother, Shyamala, raised my sister Maya and me to believe that it was up to us, and every generation of Americans, to keep on marching," she said.

And 30 years ago, I stood before a judge for the first time, breathed deep, and uttered the phrase that would truly guide my career and the rest of my career, Kamala Harris for the people," she said.

Taking a jibe at President Donald Trump, Harris said she has worked to hold his officials accountable to the American people.
