Occupy DC protesters in McPherson Square say one of their own apparently pilfered thousands of dollars in donations from the group’s bank account in an incident that shed light on just how much cash the anti-capitalism group has been given to continue a protest now in its third month. Occupy DC has raised at least $20,000 since it arrived in the District in early October, according to the group. Protesters say major labor unions like the AFL-CIO and the Service Employees International Union are among the donors to the movement, but spokesmen for both unions denied giving any cash to Occupy.
