Conservative activist James O’Keefe, who posed as a pimp in the infamous ACORN sting videos, has been arrested in New Orleans in what appears to be an attempt to wiretap the office of Democratic Sen. Mary Landrieu.

Chris Good has details from the FBI affidavit:

According to Rayes, O’Keefe and another man, Stan Dai, have admitted to federal agents that he helping plan, coordinate, and prepare for the attempted infiltration and wiretapping, and the two men who allegedly posed as telephone company workers have admitted to entering Landrieu’s office under false pretenses.

O’Keefe entered Landrieu’s office and told a staffer there that he was waiting for someone to arrive, according to the affidavit. Special Agent Rayes states that two men, Joseph Basel and Robert Flanagan, then entered the office wearing blue denim work pants, blue work shirts, flourescent vests, tool belts, and carrying hard hats, and claimed to be workers for a telephone company.

O’Keefe then recorded them with his cell phone (which the staffer noticed) as Basel asked to see the office phone, “manipulated” the handset, and tried to call it with his cell phone, Rayes states. Basel and Flanagan said they needed access to the phone system, at which point the staffer directed them to the GSA office in the building, according to the affidavit. They went there, were asked for credentials, and said they had left their credentials in their vehicle; neither of them actually work for a phone company, according to the affidavit.
