Federal officials arrested nearly 1,500 immigrants across Massachusetts last month, U.S. Attorney Leah Foley said. The big picture: Foley's announcement on Monday is the latest example of the Trump administration's efforts to ramp up immigration enforcement and paint Massachusetts as a state that's overlooking crime.

Federal immigration authorities offered few details Monday about the nearly 1,500 people arrested in Massachusetts in May as part of a monthlong “enforcement operation” that targeted individuals accused of living in the United States illegally.
