WASHINGTON: US President Joe Biden and his Republican rival and predecessor Donald Trump have easily won their presidential primaries in four more states as they are set for a 2020 rematch in November.

On Tuesday, hundreds of delegates were up for grabs in Rhode Island, Connecticut, New York and the crucial battleground state of Wisconsin.

Multiple names remained on the presidential ballots in the four states, though neither Trump, 77, nor Biden, 81, faced any major challenger.
