Crowds of union members, college students and others are adding their voices to the demonstrators who've been camped out near Wall Street.

About 1,000 students held up signs denouncing the dismal state of the economy as they marched to Foley Square in lower Manhattan on Wednesday.

At least another 1,000 people were already at Foley Square, mixing with young people who had been camped out in Zuccotti Park for the past couple of weeks.

The Occupy Wall Street protest started Sept. 17. The protesters have varied causes but have reserved most of their criticism for Wall Street. They've spoken out about unemployment and economic inequality, saying "we are the 99 percent" _ in contrast to the wealthiest 1 percent of Americans.
