And now for the real battle against Donald Trump.
Hillary Clinton clinched the Democratic presidential nomination after obtaining the required 2,383 delegates, making her the first female nominee to lead the White House.
Clinton had reached the minimum number of delegates required even before primaries in six states on Tuesday, including California and New Jersey.
Clinton will formally accept her party's nomination in July at the Democratic National Convention in Philadelphia.
Bernie Sanders, Clinton's Democratic rival, has vowed to stay in the race until the convention in hopes he can convince superdelegates to switch to his side.
Sanders has argued he is the stronger candidate to take on presumptive Republican nominee Donald Trump in the general election.
"It is unfortunate that the media, in a rush to judgement, are ignoring the Democratic National Committee's clear statement that it is wrong to count the votes of superdelegates before they actually vote at the convention this summer," Sanders campaign spokesman Michael Briggs said in a statement Monday.
