The Transport Workers Union Local 100 unanimously voted to join the protesters, the Huffington Post reports. The union boasts a membership of 38,000 people.

The protestors will reportedly march to the NYPD headquarters Friday.

Their cause has been joined by several high profile figures in the past few days, including Dr. Cornel West, Michael Moore and Susan Sarandon. Today they may add a band to that list:

Radiohead will play for the protestors this afternoon at Liberty Plaza, according to Occupy Wall Street’s official site. Or maybe not. A rep for the band denied there was any such show to the Wall Street Journal.

Meanwhile, similar protests seem to be spreading to other cities.

In San Francisco, several hundred people gathered in the city’s Financial District on Thursday to protest the banking system, the Examiner reports. Six people were arrested after staging a sit-in at a Chase bank, according to the Bay Guardian.

The DCist reports that hundreds of people in the nation’s capital are planning to protest in McPherson Square on Saturday. Protests will be held in Boston on Friday.
