Threat on Barack Obama's Life Today in New York City?: Secret Service Tackle Man After Obama Spikes the Football at Ground Zero

Witnesses who lined the parade route today as Obama spiked the football in New York City to further self-promote himself in the days since he announced Osama Bin Laden died say a man pulled out a gun when the Obama motorcade passed by.

The man, who wore a blue hat, had dark curly hair and appeared to be in his 20s, was wearing a backpack. New York Police Department officers and Secret Service agents shouted, "Get down, get down," and tackled the man at the corner of Church and Vessey Streets in lower Manhattan.

Obama had just left the World Trade Center site and his motorcade was turning from Vessey Street to Church Street when the incident occurred in front of the Church Street Station Post Office.
