Joe Biden has won Alabama's Democratic presidential primary after also winning in North Carolina and Virginia.

Black voters hold sway in Alabama's Democratic electorate, and Biden and Mike Bloomberg split the endorsements of the state's largest black political coalitions.

Thank you, Alabama!

The Alabama New South Coalition backed Mr Biden, and the Alabama Democratic Conference supported former New York mayor and billionaire Michael Bloomberg.

Mr Biden also won Virginia and North Carolina on Super Tuesday, while Bernie Sanders won the primary in his home state, Vermont.

Voting is still underway elsewhere in the country, including California, the night's biggest prize.

Meanwhile Mr Bloomberg and Representative Tulsi Gabbard of Hawaii won their first delegates thanks to American Samoa.

The island has six Democratic delegates and their caucus awarded five to Mr Bloomberg and one to Ms Gabbard, who hails from Hawaii.
