James, 72, was found guilty on all 13 counts of the indictment and could be sentenced to several years in federal prison, The New Jersey Star-Ledger reported Wednesday.

Co-defendant and former girlfriend Tamika Riley, 39, was also found guilty on all counts.

Between 2001 and 2005, Riley paid the city $46,000 for six parcels of land in a redevelopment zone that she quickly resold for $665,000, the newspaper said.

During the five-week-long trial, prosecutors called nearly three dozen witnesses who testified the mayor secretly manipulated the government approval process to give his girlfriend a windfall.

James, who served five terms as mayor of Newark, was one of the state's top Democratic power brokers.

He left office two years ago after deciding not to seek re-election.
