WASHINGTON, DC - OCTOBER 27: Hand-made signs protesting and supporting a variety of issues pile up in McPhearson Square as part of the Occupy DC and Occupy K Street demonstration a few blocks north of the White House October 27, 2011 in Washington, DC. Inspired by the Occupy Wall Street demonstrations in New York, Occupy DC and Occupy K Street are "interested in separating money from politics and improving the country?s infrastructure to fix healthcare, education, environment and the economy," according to their Web site. According to U.S. Park Police, the gathering is not illegal, but camping and cooking on park service property is against regulations. (Photo by Chip Somodevilla/Getty Images)
“Occupy D.C.” protesters are invoking a medieval folk hero and the specter of financial history for their latest demonstration.
On Saturday, protesters are planning to take part in a march on the U.S. Treasury to demand the implementation of a so-called "Robin Hood" tax.
The D.C. march is part of global protests that have been called for Saturday by the Canadian anti-capitalist group Adbusters. The group is asking governments of the Group of 20 (G20) nations to impose a 1 percent tax on financial transactions and currency trades.
The march also marks the 82nd anniversary of the Wall Street Crash of 1929 that marked the beginning of the Great Depression.
Protesters say that money raised by the tax could then be used to increase investment in public services and create more jobs
The protest begins at 2 p.m. at McPherson Square.
