This was just the latest in a series of what have been called undercover guerrilla videos by the 26-year-old O'Keefe, whose aim has been to embarrass or ensnare liberal groups.
"This is no joke. We're called to do this and we're gonna devote our lives to doing it," O'Keefe said while accepting an award for his work.
Last year, O'Keefe and a female associate posing as a prostitute taped members of the activist group ACORN advising them on how to conceal the woman's criminal activities to get a home mortgage. Other targets have included the pro-choice group Planned Parenthood and New Jersey's teachers union.
