Iran Press/ America: On a day traditionally dubbed Super Tuesday - when the most states choose who they think should be candidates - both virtually secured the nomination for their respective parties.
Republican Mr Trump won in Alabama, Arkansas, California, Colorado, Maine, Massachusetts, Minnesota, North Carolina, Oklahoma, Tennessee, Texas and Virginia, brushing aside Nikki Haley.
Meanwhile, Mr Biden appeared to win easily in 14 states, but lost in the US territory of American Samoa and faces a potentially sizeable protest vote in Minnesota, where he is still projected to win.
Despite their clear victories, a rematch between Mr Trump, 77, and Mr Biden, 81 - the first repeat US presidential matchup since 1956 - is one few Americans seem to want, based on opinion polls.
