CREW predicted there would be constitutional challenges to the Senate's decision to ask the Justice Department to investigate the controversial Coconut Road earmark.  So, Rep. Young's objection isn't a big surprise:

Rep. Don Young says the Senate overstepped its authority when it voted to seek a federal investigation of an altered earmark.

“What the Senate did was unconstitutional,” the Alaska Republican said Wednesday. “No other body can request an investigation on another body.”

The Senate included language calling for a criminal investigation in a bill (HR 1195) intended to make revisions to the 2005 highway law (PL 109-59).

Any Justice Department investigation would mean scrutiny of Young and his staff, since Young was chairman of the Transportation and Infrastructure Committee when a $10 million earmark was changed between final passage and presentation to President Bush.
