Federal prosecutors yesterday tried to debunk disgraced former state Sen. Vince Fumo's argument that he should not have to forfeit $4 million to the government.

The feds' court filing said that the defense was dead-wrong in its assertion that the feds' $4 million claim for forfeiture should be dismissed or at least limited to the $2 million amount originally sought in the indictment.

Fumo was found guilty on March 16 of 137 counts of conspiracy, fraud and obstruction of justice after a five-month trial. (Prosecutors contended at trial that Fumo defrauded the state Senate and two nonprofits of more than $4 million by, among other offenses, using Senate staffers and nonprofit resources for personal or political gain.)
