Occupiers call it the “Mockupy” — a union-backed protest camp set up on the National Mall this week with rhetoric and a look very similar to the Occupy movement. And though the Take Back the Capitol protest leaves town Friday, its very presence heightened tensions between Occupy DC and the labor unions that claim to support them.

The unions say they merely share the same goals as Occupy DC and aren’t trying to co-opt the movement. But many of the occupiers camped at Freedom Plaza and McPherson Square for two months believe the unions are trying to claim credit for Occupy’s movement and momentum.
