BERLIN (AP) — An activist group built a wall in Berlin featuring the face of Donald Trump, then tore it down in a rally to encourage Americans overseas to vote against the Republican presidential candidate.

The group Avaaz built the cardboard-block wall Friday at the landmark Brandenburg Gate, not far from the spot where former President Ronald Reagan once famously called for Soviet leader Mikhail Gorbachev to "tear down this wall."

The ersatz wall carried an image of Trump and the message: "United to Stop Trump."

Campaigner Meredith Alexander called Americans abroad the "secret swing state" and says her group is trying to ensure all eligible voters get and file their absentee ballots.

She says "there about 8 million of us who live oversees," but in the last election only 12 percent voted.
