PORTLAND — Presidential candidate Hillary Clinton is making a campaign stop at a Portland, Maine, middle school as she continues her push for the Democratic nomination.

The former secretary of state will appear at King Middle School in the state’s largest city on Friday. The event is scheduled for 4 p.m. and will be open to the public. A Clinton spokesman says in a statement says the event is a “grassroots organizing meeting.” It’s part of Clinton’s effort to build campaign infrastructure outside of the early primary states.

Clinton campaigned in Maine last year on behalf of state Democrats who were running in midterm elections. She made an appearance at a Scarborough high school gym in October in support of gubernatorial candidate Mike Michaud and others.
