PHILADELPHIA — The judge sentencing former state Sen. Vincent Fumo next week will decide today whether Fumo perjured himself on the stand during his corruption trial.

U.S. District Judge Ronald Buckwalter also must calculate the extent to which the multimillionaire Philadelphia Democrat defrauded the state Senate and two nonprofits.

Prosecutors put the total at more than $4 million. Fumo's lawyers are trying to reduce the figure to avoid a harsher sentence that applies to frauds of more than $2.5 million.

Fumo wielded nearly unrivaled power in the Pennsylvania Senate for much of his 30-year career.

Now 66, he faces a lengthy prison term after his March conviction on all 137 counts. A probation report puts his sentencing range at 21 to 27 years, but Buckwalter could impose a tougher or more lenient sentence.

The jury found that Fumo used staff and resources of the Senate and nonprofits for personal and political chores.

Fumo, whose net worth was estimated by lawyers at $9 million to $11 million, also faces millions in possible restitution.
