Sen. Dianne Feinstein (D-Calif.) expressed a cautious view of the Occupy Wall Street movement on Wednesday, seemingly giving voice to a growing uncertainty on the left that the ongoing protests are going anywhere.

“There are all kinds of different agendas going on [and it is] hard to figure out what people want,” Feinstein said Wednesday, according to the Los Angeles Times.

"I don't think" the protesters have the right to "Occupy forever," she added. "I  don’t think people, for example, can sleep in a square for weeks on end. You have to have some order to it."

Protesters have been camped out in front of City Hall in Los Angeles for two weeks, and some council members have expressed a growing unease with the impact they are having and the length of their stay.

Occupy LA issued a statement on their Facebook page in response to Feinstein and similar comments made about the length of protesters' stay by Los Angeles Mayor Antonio Villaraigosa. The statement notes that while protesters appreciate Feinstein's and Villaraigosa's acknowledgment of their First Amendment rights, the movement is going through a democratic "process" that can "sometimes be lengthy."

The Occupy Wall Street movement, which started in New York City's Financial District and has spread to various cities from there, is inspired by frustration with corporate greed, according to organizers.
