ACORN Foe Charged in Sen. Phone Hack Plot

Last updated 7:44 p.m. ET

A conservative activist who posed as a pimp to target the community-organizing group ACORN and the son of a federal prosecutor were among four men arrested and accused of trying to tamper with phones at Democratic Sen. Mary Landrieu's office.

Landrieu called the allegations "unsettling." She called it a "very unusual situation" and said she is "as interested as everyone else about their motives and purpose."

Activist James O'Keefe, 25, recorded two of the other suspects with his cell phone as they walked into the office dressed like telephone repairman and said they needed to fix problems with the phone system, according to an FBI affidavit.

A source tells CBS News that the aim was apparently to try to catch Sen. Landrieu talking negatively about her constituents.

A federal law enforcement official said one of the suspects was picked up in a car a couple of blocks away with a listening device that could pick up transmissions. The official spoke on condition of anonymity because the information was not part of an FBI affidavit that described the circumstances of the case.

O'Keefe said "veritas," Latin for truth, as he left a suburban jail Tuesday with suspects Stan Dai and Joseph Basel, both 24. All declined to comment.

"There will be a time for that," Dai said.

As he got into a cab outside the jail, O'Keefe said, "The truth shall set me free." His biography on a Web site where he blogs says he works at VeritasVisuals.com, though that Web site does not currently work.

The fourth suspect, Robert Flanagan, the son of Shreveport-based acting U.S. Attorney Bill Flanagan, was not with them. It was not immediately known if he had already been released on the $10,000 bail set for each suspect.

It sounded like a Watergate-style operation, but federal officials have not yet said why the men wanted to interfere with Landrieu's phones, whether they were successful, or even if the goal was political espionage.

According to the FBI affidavit, Flanagan and Basel showed up at Landrieu's office Monday morning carrying white hard hats and dressed in jeans, blue work shirts, fluorescent green vests and toolbelts. They told an employee they were there to fix problems with the phone system. O'Keefe told an employee he was there waiting for someone.

The affidavit says Basel asked for access to a phone at the reception desk, then manipulated the handset and tried to call the phone with his cell phone, but said he could not get through. Flanagan tried to call as well, according to the affidavit.

They said they needed to work on the main system and asked where the telephone closet was. They were directed to another office in the building, where they again said they were telephone repairmen and an employee asked for their credentials. They said they had left them in their vehicle.

They were arrested later by U.S. marshals. Details of the arrest were not available. Dai was also arrested, but Letten's office said only that he assisted the others in planning, coordinating and preparing.

Landrieu, a moderate Democrat, declined comment Tuesday through spokesman Aaron Saunders. Saunders did say Landrieu was in Washington, not in her office, when the men showed up Monday. Landrieu has been in the news recently because she negotiated an increase in Medicaid funds for her state before announcing her support for Senate health care legislation.

Bill Flanagan's office confirmed his son was among those arrested, but declined to comment further.

An FBI criminal complaint charging the men was unsealed Tuesday. None of the defendants, each wearing red prison jumpsuits, commented at a court hearing held in the afternoon. All four were charged with entering federal property under false pretenses for the purpose of committing a felony.

Since it is a federal office building, the crime they allegedly committed is punishable by up to ten years in prison and a $250,000 fine, reports CBS Radio News' Bob Fuss.

"It was poor judgment," Robert Flanagan's lawyer, Garrison Jordan, said in a brief interview outside the courthouse. "I don't think there was any intent or motive to commit a crime."

Michael McHale, chairman of the Louisiana Democratic Party, referred to the episode as "Louisiana Watergate" in a statement Tuesday and urged authorities to prosecute "any wrongdoers to the fullest extent of the law."

O'Keefe was the brains behind a series of undercover videos that have caused major problems for ACORN - the Association of Community Organizers for Reform Now.

He managed to do what Republicans have been trying to for years - hurt the political affiliates of ACORN, which have registered hundreds of thousands of voters in urban and other poor areas of the country.

By producing undercover videos shot in ACORN offices, O'Keefe brought a firestorm of criticism that the group was helping its low-income clients break the law.

Using a hidden camera, O'Keefe, posing as a pimp and accompanied by a young woman posing as a prostitute, shot videos in ACORN offices where staffers appeared to offer illegal tax advice and to support the misuse of public funds and illegal trafficking in children.

Edited videos of those visits to ACORN offices were first posted on biggovernment.com, a site run by conservative Andrew Breitbart.

In a statement e-mailed to The Associated Press, Breitbart said: "We have no knowledge about or connection to any alleged acts and events involving James O'Keefe at Senator Mary Landrieu's office. We only just learned about the alleged incident this afternoon. We have no information other than what has been reported publicly by the press. Accordingly, we simply are not in a position to make any further comment."

In the past, Breitbart has said O'Keefe - now a paid contributor to biggovernment.com - is an independent filmmaker, not an employee.

O'Keefe has been sued in Pennsylvania and Maryland based on the ACORN videos; he does not have an attorney of record in either case and attempts Tuesday to locate a lawyer who might represent him were not successful.

ACORN calls itself the largest grass roots community organization of low- and moderate-income people in the country, claiming over 400,000 families, more than 1,200 neighborhood chapters in about 75 cities.

Until the controversy last year over the videos at ACORN offices, 10 percent of ACORN's funds came from federal government grants. In September, Congress blocked previously approved funds from going to the group.
