evidence: Harris’ record on immigration has been marred by policy blunders. [...] Kerri Talbot, the executive director of the national advocacy organization Immigration Hub, called Harris a "strong defender and champion of American families, including their immigrant family members" in a statement Sunday. [...] When she was the district attorney in San Francisco, she backed a city policy that turned over to federal immigration authorities migrant juveniles suspected of committing a felony. In 2019, Harris’ campaign told CNN "this policy could have been applied more fairly."
