It's day 19 of Occupy Wall Street and it's expected to be the biggest day yet of the anti-corporate demonstrations.
Thousands of people coming from dozens of community organizations and labor unions are expected to descend upon Manhattan's Financial District.
From Occupy Wall Street:
On October 05, 2011, at 3:00 in the afternoon the residents of Liberty Square will gather to join their union brothers and sisters in solidarity and march. At 4:30 in the afternoon the 99% will march in solidarity with #occupywallstreet from Foley Square to the Financial District, where their pensions have disappeared to, where their health has disappeared to. Together we will protest this great injustice.
According to the group's website, those planning to join the demonstrations include United NY, SEIU 1199, United Federation of Teachers, Working Families Party and MoveOn.org. The Transit Union Workers and AFL-CIO are also expected to participate.
The Occupy Wall Street movement encouraged college students nationwide to stage walkouts at 2 p.m. today.
On Saturday, more than 700 protesters were corralled on the Brooklyn Bridge and arrested.
