STATEN ISLAND, N.Y. -- Cops have already begun arriving outside Rep. Michael Grimm's New Dorp office, ahead of a planned protest on the Republican congressman's Colombia trade vote.

A group called the Occupy Wall Street Trade Justice sent out a press release this week promising to mark All Soul's Day by holding a symbolic funeral in front of Grimm's office "to mourn the approximately 3,000 union organizers assassinated by government-linked narcoterrorist paramilitary groups since 1986 and other victims of human rights atrocities in Colombia."

The press release said the protest would start 1:45 p.m.

Organizers say several other groups will be participating.

Last month, Grimm voted for a free-trade agreements with Colombia, Panama and South Korea.

He said the measures are expected to create 250,000 jobs and estimated to increase U.S. exports by $13 billion, and add $10 billion to the GDP.

Officers on New Dorp Lane are wearing a large number of plastic handcuffs from their belts.

Grimm is in Washington today, and not in his Staten Island office.
