Vermont Sen. Bernie Sanders suspended his campaign for the 2020 Democratic presidential nomination on Wednesday in a conference call with staff, his campaign said in a statement.

But he saw his hopes for the nomination slip away in March after a series of wins for Joe Biden, the former vice-president who is now the presumptive nominee to challenge Donald Trump in the general election in November.
