Democrats in the US Senate want an investigation over an earmark requested by Rep. Don Young (R-AK), a unapologetic defender of his pork:

The Senate may seek a federal investigation into a 2005 earmark on a highway funding bill that was mysteriously altered after Congress approved the measure but before President Bush signed it.

The $10 million earmark, originally designated for improvements to Interstate 75 in Lee and Collier Counties in Florida, was changed to direct the money to build an interchange in Lee County, an apparently violation of congressional rules.

"This wasn't an ordinary earmark," Sen. Charles Schumer, D-New York, said, defending the decision by Democratic leaders to invite the Justice Department to probe internal congressional practices. "It was the specific circumstances here that are highly unusual."

Rep. Don Young, R-Alaska, who was then the chairman of the transportation committee and chief author of the bill, says he asked for the initial project money during the 2005 congressional session for "widening and improvements for I-75 in Collier and Lee counties."

But before the bill got to the President's desk for his signature, the wording of the earmark was changed and the $10 million was redirected to build the "Coconut Road interchange I-75, Lee County."

Democrats widely believe Young directed someone to change the language. They note that as the bill was moving through Congress, Young received $40,000 in campaign contributions from local business leaders who stood to gain from a new highway interchange at that location.

If Senate leaders want the DoJ to investigate Young, they should go ahead and investigate nearly $30,000 in campaign contributions to the Democratic Senatorial Campaign Committee, which is headed by Chuck Schumer, and Hillary Clinton by Alan Gerry, who was seeking a $1 million earmark for the hippie museum at Woodstock.

My point is that there is plenty of this type of questionable behavior going on in Congress and those pointing fingers in this case are just as guilty. And I'm not defending Don Young. He is corrupt and I hope the people of Alaska boot him from office, but he only an example of the corruption.
