The federal judge presiding over Senator Ted Stevens’ corruption case excluded some evidence on Wednesday. Judge Emmet G. Sullivan of Federal District Court argued that the Justice Department prosecutors used documents although they were aware of the fact that they contained lies.

Prosecutors wrapped up their case on Thursday after calling a final witness who was brought to court to testify about his work in renovating the Republican senator’s house. Senator Stevens is accused of lying on his financial disclosure forms so he could hide approximately $250,000 which he received from Alaska oil services firm VECO Corp.

The prosecution brought to court David Anderson, the nephew of VECO’s CEO Bill Allen, and a welder for the company, who worked on the senator’s house seven ears ago. Anderson told the jury that he spent months working on the project along with other VECO employers. He said he often worked 10 hours a day, six days a week.

The judges advised the jury not to take into consideration the prosecutors’ records because Anderson actually was in Oregon for much of the time when the records showed that he was working on the senator’s house.

“The government knew the documents were lies” said Judge Sullivan in a special hearing.

Sullivan refused to dismiss the charges and rejected the defense request for acquittal. Senator Stevens, 84, is seeking re-election next month after 40 years in Senate. He is the longest-serving Senate Republican in history.

When asked about the accusations brought against him, he denied everything and said his wife had been taking care of the financial matters.
