Washington, March 9 (TIWN) California Senator Kamala Harris on Sunday endorsed current front-runner and former Vice President Joe Biden as the Democratic party's US presidential candidate, saying the country and the people "need him now more than ever".

"I really believe in him and I've known him for a long time."  Harris said she would be joining Biden at a Detroit event on Monday.
