The PSI quickly asked the FBI, DOJ and DOL to turn over their files on the Presser probe. Although some members of Congress accused the FBI of misleading Justice officials about Presser's role as a criminal informant, FBI Director William H. Webster revealed that he had informed Attorney General William French Smith about Presser's role in May 1983, and that on at least two other occasions that year DOL and DOJ investigators in Cleveland were told Presser was an FBI source. After a year of hearings, the Subcommittee on Investigations concluded in its report that rivalries among federal law enforcement agencies and poor supervision of the FBI by DOJ superiors led to the cancellation of the prosecution. The report also said the public nature of the snafu had set back prosecutorial efforts by several years. Subcommittee members also expressed their anger at what they termed "an overall FBI attitude of obfuscation, intransigence and delay" in the Presser case. While the Senate subcommittee investigation continued, other developments led to the reinstatement of the prosecutorial effort. Realizing that there was public pressure to resume prosecution despite his role as an FBI informant, Presser claimed that he had been given permission to engage in payroll padding by his FBI contacts. DOJ and FBI rules condone the commission of certain crimes so long as the crimes meet certain guidelines, are used solely to protect sources, and permission is secured in advance from top-level DOJ officials. Presser's lawyers argued that the permission given to him by FBI agents should bar any prosecution. Presser's attorneys also said that Presser had requested FBI permission several times to dismiss the "ghost employees" and that FBI agents had turned his requests down. Presser's claims were undercut when two criminal investigations into FBI behavior began in August 1985. In August 1985, the Department of Justice's Office of Professional Responsibility began an investigation into whether the three FBI agents handling Presser had told their FBI and DOJ supervisors the truth about their actions and promises. Senior DOJ officials told investigators that the agents did not reveal that they had authorized criminal activity. Investigators also claimed that senior DOJ officials failed to pass on information about Presser's role to the Attorney General's office or to DOL (a charge FBI Director Webster denied). At the same time, a federal grand jury in Cleveland began a criminal investigation into DOJ's handling of Presser. Presser's uncle, who was also a Teamster official, had been convicted of embezzlement. After just four months, the grand jury concluded that FBI and DOJ officials had illegally withheld information about Presser's role from the defense.
