Bernie Sanders Announces He Is Running for President

Senator Bernie Sanders, Independent of Vermont, announced Thursday that he was running for president as a Democrat, injecting a progressive voice into the contest and providing Hillary Rodham Clinton with her first official rival for the party’s nomination.

Avoiding the fanfare that several Republicans have chosen so far when announcing their candidacies, Mr. Sanders issued a statement to supporters that laid out his goals for reducing income inequality, addressing climate change and scaling back the influence of money in politics.
