The conservative filmmaker arrested this year for an undercover attempt to tape staffers at a U.S. senator's office said his next target -- the Census Bureau -- is another example of government waste.
James O'Keefe, fresh off sentencing for his role in the attempted sting on Sen. Mary Landrieu's Louisiana office in January, signed up to work for the Census in hopes of exposing what he alleges is the bureau's waste of taxpayer money.
"You're on notice...if you are doing things behind closed doors, we will find you and we will film you," O'Keefe said.
O'Keefe and friend Shaugn Adeleye signed up in May to work for the Census Bureau in New Jersey and Louisiana, respectively.
They each attended paid training courses: O'Keefe earned $18.25 an hour and Adeleye made $13.25 an hour.
The two quit after a few days and, O'Keefe said, his time with the Census Bureau proved his theory that the government entity was wasting money.
"Over the course of two days I was paid for as many of 3 ½ to 4 hours of work I didn't do," O'Keefe said.
"This is just the tip of the iceberg," he said.
When O'Keefe confronted his supervisor about getting paid for hours he didn't work, she told him not to worry about it.
"We all left early," O'Keefe could be heard telling his supervisor on the tape.
"You got paid for two hours more then," his supervisor replied.
"Yeah, so that's all I'm concerned about," O'Keefe told her.
"I would say don't be concerned...you did your best to, you know, to bring it to our attention. I don't, I don't think anyone's going to be questioning it, except for you," she told O'Keefe. "So I would just let it go." When O'Keefe's colleague, Adeleye, approached his supervisor in Louisiana showing that he was paid for hours he did not work, his supervisor said "I'd throw it away. But I mean, you want to keep it for your records, fine."
But the video also shows a supervisor advising trainees to keep careful and accurate records of their mileage.
"This is not a big issue here but when you start doing this enumeration thing you want to make sure you are watching your miles, ok," one supervisor said on the tape. "Set the odometer, and everyday record it, no estimating, no guessing. That's part of their ability to audit you - would be to look at your miles - look at the places you went to, and if it didn't add up..."
O'Keefe said that same supervisor also gave a "70 minute lunch break" while they got paid for much of that time.
The supervisor said, on the tape, going forward they would only get 30 minutes for lunch. They were given the 70 minutes because they were new and may be unfamiliar with their way around the area where the training session was held, he explained.
In a statement released to ABC News, Stephen Buckner, a spokesman for the Census Bureau, said, "After the Census Bureau's stringent background check procedures, Mr. O'Keefe quit before further action could be taken."
O'Keefe's short stint as a Census worker is the latest in a controversial string of attempts to expose alleged government waste or wrongdoing. He said he considers himself an investigative journalist, while critics have labeled him a political activist.
