A relentless summer sun and 92 degree temperatures didn't stop thousands of demonstrators who rallied at City Hall Plaza and then marched to the Boston Common as part of a nationwide "Families Belong Together" protest against President Trump’s “zero-tolerance” immigration policies, including the recently ended practice of separating children from their parents. Numerous local organization representatives as well as U.S. Sens. Elizabeth Warren and Ed Markey and Rep. Joe Kennedy, Jr. joined the demonstrators in calls for an end to zero-tolerance policies on immigration.
