Kamala Harris accepted her historic vice presidential nomination Wednesday after being introduced by three of her closest female relatives, a symbol of the central role women have played in her trailblazing life and could have in November's election. Known as "Momala" to her two step-children, the 55-year-old US senator and daughter of immigrants has embraced her status as the first woman of color on a major party ticket, and outlined a future of possibilities if she and presidential candidate Joe Biden defeat President Donald Trump.
