A Teamsters Union report to be released Thursday found no mob influence over national union officials, contradicting earlier findings from another Teamsters investigator.

The previous report also accused union officials of shutting down an investigation of mob ties to the local union, another finding disputed by Thursday's report.

According to the new findings, sources for the previous investigation were poorly chosen and the inquiry was put on hold because it cost the Teamsters $15 million and was getting too expensive.

On Wednesday, the new document was branded a "whitewash attempt" by Edwin Stier, who wrote the first report and is a former federal prosecutor.

He said Thursday's report is an attempt "to cover up the corrupt activities of Teamsters officials that we were investigating. My opinion is it was a predetermined result--they intended to discredit me."

Stier said the latest inquiry does not address accusations that Chicago Local 727 union officials bilked millions of dollars from the union's dental benefits funds or allegations that a foreman in the city's Hired Truck Program solicited bribes and made as much as $90,000 a year by secretly owning a truck used in the program.

Pat Szymanski, Teamsters general counsel, said Ed McDonald, another former federal prosecutor, had to be hired last year because Stier did not accomplish what he was hired to do.

Stier "wasn't doing a good job of it," Szymanski said. "I couldn't trust him anymore."

In 1999, Stier was hired by Teamsters Union President James Hoffa to prove the union was capable of policing itself, as well as to create a new code of ethics, after a 1989 federal racketeering lawsuit charged the union was controlled by the mob. The federal government set up an Independent Review Board to monitor the union, and Teamsters officials hoped to end that surveillance by proving they could police themselves.

Hoffa chose Stier because he had specialized in organized crime as a federal prosecutor.

In April 2004, however, Stier resigned after writing a report accusing Teamsters officials of caving in to mob influence when it came time to investigate corruption in Chicago locals.

"I warned Hoffa and the executive board that the test would come when they had to hold friends and political associates accountable," Stier said. "They hired me in spite of my warning."

After the April 2004 report, the union hired McDonald to write a second report investigating Stier's claims.

"We found that everything he did was wrong," McDonald said. "We disagree with his conclusions."

McDonald said Stier was to create a new code of conduct, which was to be presented to the Teamsters board, then to the federal government in an attempt to replace the federal monitors.

"The Justice Department was not satisfied," McDonald said. "They did not approve of the code. And it was never submitted to the board because it was pointless."

Stier disagreed. "The board had seen the draft," he said. "There was never a rejection of this document by the federal government. The federal government made comments on it."

McDonald said Stier didn't seek board approval before going ahead with investigations, interfered in the federally run Independent Review Board's investigations, and wasted money by looking into issues the government was already checking out.

But Stier said he did not interfere with any independent review investigations because he did not want to harm an investigation or cost the union more money.

McDonald also said Stier's sources for the report were "unreliable" because one of them gave differing accounts about offering Hoffa a bribe, and the others would not give up their original sources of information.
