Boston Mayor Michelle Wu has vowed to find out from US Immigration and Customs Enforcement who they’re arresting in her city and why. But despite repeated efforts to get answers, federal immigration authorities have refused to provide even basic details,

Director Todd Lyons said on Wednesday that the federal law enforcement agency will “flood the zone” with immigration agents in Boston after Mayor Michelle Wu (D) fired back at President Trump’s administration over the city’s sanctuary policies.

Mayor Michelle Wu hit back at ICE Director Todd Lyons’ vow to “flood” Boston in response to her refusal to strip its sanctuary protections, saying that it doesn’t make sense for the feds to target a city known for being among the country’s safest.
