BALTIMORE (AP) — Gov. Martin O’Malley is encouraging people to volunteer on a national day of service to mark the anniversary of the Sept. 11 attacks.

O’Malley attended an event Wednesday that called attention to the Baltimore Community ToolBank, which loans tools and equipment for 3 cents on the dollar to charitable groups and community organizations.
