The Senate is actually proceeding with its effort to get to the bottom of the "Coconut Road" earmark scandal.  And, by get to the bottom, Senators are actually pushing for a criminal investigation:

The Senate moved yesterday toward asking the Justice Department for a criminal investigation of a $10 million legislative earmark whose provisions were mysteriously altered after Congress gave final approval to a huge 2005 highway funding bill.

In what may become the first formal request from Congress for a criminal inquiry into one of its own special projects, top Senate Democrats and Republicans have endorsed taking action in connection with the earmark that Rep. Don Young (R-Alaska), former chairman of the House Transportation and Infrastructure Committee, inserted into the legislation.

"It's very possible people ought to go to jail," said Sen. Barbara Boxer (D-Calif.), chairman of the Environment and Public Works Committee, which oversees highway funding.
