THURMONT, Md. (AP) — Maryland Gov. Martin O’Malley is joining a campaign for world hunger relief aimed at the Group of Eight economic summit at Camp David.

The Democratic governor sent a tweet that is among hundreds of short messages the Washington-based group One spray-painted Wednesday on state Route 77 near Thurmont. The presidential retreat is located inside nearby Catoctin Mountain Park.

O’Malley’s message reads: “Together, let’s end hunger.”

An O’Malley spokeswoman says the governor joined the campaign because he has set a goal of ending childhood hunger in Maryland by 2015.
