Van Jones, who served as President Barack Obama's environmental adviser until September 2009, said progressives are going to launch an October offensive against the Tea Party.

Last June, Jones launched a progressive group called Rebuild the Dream to focus on job creation and to oppose the influence of the Tea Party in American politics.

Speaking on MSNBC's The Last Word with Lawrence O'Donnell this week, Jones said: Everybody should hold onto their seats. October is going to be the turning point when it comes to the progressive fight back. You can see it coming.

Referring to potential signs of this turning point, Jones said, Warren Buffett comes out and says, 'Look, we've got to do something to raise taxes and to do better by America,' and you've got these young kids who are going out there on Wall Street. In the latter case, he was speaking of the Occupy Wall Street protesters, who have been camped out in Zuccotti Park in New York's financial district for the past couple of weeks.

There's a generation of Americans who are looking around and saying, 'What is the American Dream going to look like for me?' They're going to be standing up, he said.

You are going to see an American Fall, an American Autumn, just like we saw the Arab Spring, said Jones said.

You can see it right now with these young people on Wall Street. Hold onto your hats: We're going to have an October offensive to take back the American dream and to rescue America's middle class.
