If Not Now is a movement of American Jews calling for an end to U.S. support for what they call Israel's "apartheid system."
The large banner read: "Jews Say: Let Gaza Live!"
People at the top of the tower also held signs that read "Congresswoman Pelosi," "Senator Pedilla," and "Senator Butler."

The banner hung for about 10 minutes before the group removed it as police were arriving.
A rally was also being held at the foot of Coit Tower on the front steps.
This demonstration comes the same day Israeli Prime Minister Benjamin Netanyahu said he has told the US that he opposes the creation of a Palestinian state.
