Boston Mayor Michelle Wu signed an executive order that seeks to put pressure on the Trump administration to shed light on ICE’s “secret police tactics” that she says have been used in the city and country as part of the feds’ immigration crackdown.

Boston Mayor Michelle Wu went on offense against the Trump administration, declaring she signed an executive order asking ICE to provide information on who they are arresting in the city.

As widespread reports of immigration enforcement officers making arrests wearing masks and refusing to provide information about detainees spread fear in immigrant communities, Boston is trying to get more transparency from the federal government about these operations.
