Conservative filmmaker James O’Keefe was sentenced to three years of probation, 100 hours of community service and a $1,500 fine after he pleaded guilty on Wednesday to misdemeanor charges stemming from his involvement in a break-in at Sen. Mary Landrieu’s (D-La.) office.

In January, O’Keefe and three others were arrested by federal authorities at Landrieu’s office on allegations of phone-tampering.

{mosads}Prosecutors initially said they caught four individuals in the process of committing a felony, but the charges were later reduced to misdemeanors. 

O’Keefe got the toughest sentence. His co-defendants, Stan Dai, Joseph Basel and Robert Flanagan, each got two years of probation, 75 hours of community service and the same fine as O’Keefe.

O’Keefe became famous in September of last year for secretly taping workers from the community activist group ACORN offering him and a partner financial advice while they posed as a pimp and prostitute.

His video resulted in Congress removing some funding for ACORN, which for           several years has been the scourge of conservative activists who say the group participated in voter fraud.

O’Keefe claimed he and his co-defendants were investigating allegations that Landrieu was ignoring constituent calls during the healthcare debate and were not planning to do anything illegal.
