BOSTON (AP) — The governor of Massachusetts has formally asked the federal government to declare a disaster in 10 counties after a record-setting series of winter storms.

Gov. Charlie Baker’s request was made Friday in a 22-page letter to President Barack Obama, delivered through the Federal Emergency Management Agency.
