The Hillary Clinton campaign opened a new office in Augusta on Sunday, the fourth regional office in the state.

The office opened in advance of the March 6 Democratic caucus, which will be held at various sites across the state. Other Hillary Clinton offices were opened in the last week in Portland, Bangor and Lewiston. The Augusta office is located at 225 Water St.

Earlier this month, supporters of Vermont Sen. Bernie Sanders opened a campaign office in Portland.
