NEW YORK (Reuters) - U.S. presidential candidate Bernie Sanders will return to the campaign trail in New York City on Saturday, nearly three weeks after a heart attack that raised concerns about his viability in the Democratic race to pick a challenger to President Donald Trump.
U.S. Representative Alexandria Ocasio-Cortez, one of the leaders of the party's progressives and a frequent target of Trump attacks, will join the "Bernie's Back" rally in Queensbridge Park and formally endorse Sanders for the White House, the campaign said.
