Indian-origin Democrat endorsed by President Obama

45-year-old Harris, who is contesting for the Attorney General of California, has done a remarkable job, said Obama.

However, at a time when Obama's popularity rating is at low ebb, the impact of his endorsement would be known only after the results of the November 2 elections.

In an email distributed by the Democratic National Committee/Organising for America on Saturday, Obama said Kamala Harris has always been a strong voice for Californians.

Obama credited Harris with several achievements including launching an early intervention programs to reduce the cycle of repeat offenders.

"As San Francisco District Attorney, she launched early intervention programs to reduce the cycle of repeat offenders. She created her office's first Child Sexual Assault Unit and first Environmental Justice Unit. She prioritised the prosecution of financial predators, processing over 450 consumer complaints in 2009 and forming the state's first stand-alone Mortgage and Investment Fraud Unit," Obama said.

"Now she's running to be California's attorney general, and I am proud to stand by her. She is someone who understands the needs of all Americans, and I need allies like that fighting for change across the country...," he said.

"Kamala has done a remarkable job in San Francisco. Now it's time to send her to Sacramento so she can get those same results for all Californians -- but she needs our help if she's going to win this race," Obama said in his endorsement message.

Harris is running against Steve Cooley –a Republican candidate who currently serves as district attorney for Los Angeles County.

Harris has an Indian-American mother and a Jamaican-American father.
