U.S. Sen. Lisa Murkowski is questioning the Justice Department's decision not to pursue charges against former Veco Corp. Chairman Bill Allen in a child sexual abuse investigation.
In a letter written Saturday to Attorney General Eric Holder, Murkowski says she was "shocked and dismayed" to read about the decision. The letter asks Holder to find out why prosecution was declined and to report those findings to the senator's staff.
Allen was the government's star witness in corruption cases that included former U.S. Sen. Ted Stevens, who died last week in a plane crash. Stevens was convicted, but a judge later tossed the conviction because of prosecutorial misconduct.
Allen pleaded guilty to bribery and tax violations and is serving three years at a federal prison in California.
