Massachusetts officials have spent nearly $1 billion on illegal aliens but have refused to give legal residents details about those expenditures, the state Republican Party claims.

The Massachusetts Republican Party has submitted Freedom of Information requests to more than a half-dozen state agencies, including the office of Democratic Gov. Maura Healey, to uncover more information about payments made in connection with illegal immigrants, according to a party press release issued earlier this week.

In a statement, Massachusetts Republican Party chair Amy Carnevale alleged that the state's spending on illegal aliens has been "shrouded ... in secrecy" and designed to keep "residents in the dark."
