(Combined Sources) Massachusetts officials are voicing concern about the U.S. Postal Service as voting by mail has taken center stage this election cycle because of the coronavirus pandemic. Unionized postal workers complain the federal agency has removed at least a dozen mail sorting machines in the state as part of a nationwide reduction plan. Massachusetts Attorney General Maura Healey joined other state attorneys general on Tuesday in a lawsuit meant to halt changes President Donald Trump’s administration has made to the embattled agency ahead of the election. Massachusetts Secretary of the State William Galvin called the agency cutbacks “politically motivated” while congressional lawmakers held events with Massachusetts postal workers Tuesday.
