New York ( CNN ) -- Protesters rallied in downtown New York City Thursday to voice their anger over what they perceive as the roles Wall Street and big banks played in America 's economic crisis . Marching from City Hall to Wall Street , the protesters chanted `` good jobs for all , '' and held signs with messages including `` Hold banks accountable , '' `` Make Wall Street Pay , '' and `` Reclaim America . '' The AFL-CIO organized the rally , and union President Richard Trumka addressed the crowd , saying , `` How long will we allow the spirit of greed to continue to drive us into economic holes ? '' The National People 's Action , a group that was involved in organizing the protest , said in a news release that demonstrators represented unemployed workers , foreclosure victims and community activists . Protester Gerard Pettine said he just wants Wall Street to be held accountable for its involvement in the economic collapse . `` They need to have some integrity and some honor and do the right thing , '' Pettine told CNN . Protester Elizabeth Soto , who came with her brother to the rally , was concerned about the lack of job creation . `` We are here to say Wall Street 's got to help Main Street , '' she said . `` We supported the stimulus bill , which bailed out Wall Street , but we expected the jobs to come back to Main Street . '' The New York Police Department estimated that 6,000 people participated in the rally . Earlier Thursday , as part of a larger `` day of action '' against Wall Street , protesters descended upon the headquarters of two New York City banks -- JP Morgan Chase and Wells Fargo -- leaving letters for the banks ' chief executive officers . The letters , according to the news release from the National People 's Action , said that the banks have an opportunity `` to step up to the plate and be leaders in rebuilding the American economy . '' JP Morgan spokesperson Mike Fusco declined to comment on the letter , but said that there were a `` couple dozen '' protesters who were in the building for less than a half hour . Fran Durst of Wells Fargo said that about 100 protesters flooded their building 's lobby and tried to deliver their letter to the bank 's CEO . Durst said the event did n't cause a major disruption to the bank . Other protests were scheduled in San Francisco , California ; Kansas City , Missouri ; and Charlotte , North Carolina , according to the National People 's Action news release . CNN 's Mary Snow , Jennifer Rizzo , Cassie Spodak , and Kristen Hamill contributed to this report .
