The federal investigation of former Rep. Curt Weldon (R-PA) has nabbed another one.

Pleading guilty in federal court today was Cecelia Grimes, Weldon’s very good friend and a former lobbyist.

Grimes admitted to destruction of evidence and could face up to 20 years in prison, according to the U.S. Department of Justice.

The case goes back to October 2006, just after the feds began investigating Weldon for alleged nepotism, particularly concerning the lucrative lobbying contracts awarded to his inexperienced daughter.

Grimes admitted today that just a few days after the feds served her with a subpoena, she stuffed a stack of documents into a trash bag and put it on the curb outside her home for pick up. The FBI later retreived those documents, which included records of her travel plans and Weldon’s campaign.

She also told a federal judge that she threw her Blackberry into a trash can at a fast food restaurant in Pennsylvania so the FBI could not recover the emails stored on it.

The court documents refer to Weldon only as “Representative A.”

This federal investigation probably contributed to Weldon’s failure to win reelection in 2006, But so far, none of this seems to be getting in the way of Weldon’s new career as an international arms dealer.
