Rep. Don Young (R-Alaska) announced Wednesday that the Justice Department will not prosecute him in a federal corruption investigation that targeted his home state.

Young’s office released a one-paragraph statement highlighting his cooperation with federal investigators, although it did not disclose specific allegations. Young, who has held Alaska’s only House seat since 1973, is up for re-election this year.

“Congressman Young’s legal team has been notified that after full cooperation from the Congressman, the Public Integrity Section of the Department of Justice has concluded their investigation and declined prosecution of Congressman Young,” the statement said.

Young, who has spent more than $1 million on legal fees since 2007, has previously acknowledged the federal investigation, stating in April 2008 that he had “worked fully with the Department of Justice.” He stepped down from his ranking post on the Natural Resources Committee in December 2008, citing the investigation.

In court documents filed in October 2009, former oil executive Bill Allen, who was sentenced for his role in an Alaska bribery scheme, revealed that he told the Justice Department in 2007 that he provided Young with more than $100,000 worth of gifts that the Congressman never reported.

Young has also faced scrutiny over his role in providing a $10 million earmark for a Florida transportation project known as Coconut Road, which benefited a contributor to the Alaskan’s campaigns. The Justice Department declined in the past to confirm whether it is investigating that earmark.
