U.S. presidential hopeful Bernie Sanders returned to the campaign trail in New York City on Saturday, three weeks after suffering a heart attack, and pledged to resume at full throttle his battle against the business and political establishment, including members of his own Democratic Party. Sanders, one of 19 Democrats fighting to take on Republican President Donald Trump at the polls in November 2020 was introduced by U.S. Representative Alexandria Ocasio-Cortez, one of the leaders of the party’s progressives and a frequent target of Trump’s attacks.
