Joe Biden secured several major victories in Tuesday’s three Democratic presidential primaries.
The wins expand his burgeoning lead in the race to challenge President Donald Trump in November.
Biden's dominating wins in Florida, Illinois, and Arizona sent a clear signal that Democrats are rallying behind him.
The victories also raise questions about whether rival Bernie Sanders should continue his campaign.
Biden has taken the lead in the Democratic race in the past two weeks, scoring 16 victories in the last 21 contests.
