Biden wins enough delegates to secure Democratic nomination

US President Joe Biden clinched the Democratic nomination for the second straight election on Tuesday.

It would be the first US presidential election rematch in nearly 70 years. Biden became the presumptive nominee of his party when he won a sufficient number of delegates in Georgia. That pushed Biden's count past the 1,968 needed to win a majority of the delegates to the Democratic National Convention in Chicago in August. That's where his nomination will be made official.
