US Senator Bernie Sanders suspended his presidential campaign Wednesday, clearing the way for rival Joe Biden to win the Democratic nomination and challenge incumbent Donald Trump in November.

The feisty 78-year-old democratic socialist shook up the 2020 race with his relentless pursuit of "economic justice" for all Americans and a demand for universal health care. But he acknowledged his campaign fell short, as party voters determined Biden would be a stronger candidate to go up against Trump in the general election.
