Christopher Kelly, former chief fundraiser for Rod Blagojevich, is sentenced to 37 months in prison on tax charges

Christopher Kelly, a former adviser and chief fundraiser for former Gov.

Rod Blagojevich, was sentenced to 37 months in prison today on federal tax fraud charges for concealing his use of corporate funds to cover gambling debts.

Kelly had faced up to 4 years in prison. He pleaded guilty to the charges in January, admitting he underreported his roofing company's profits by nearly $500,000 from 2001 through 2005.

Prosecutors said Kelly placed millions of dollars of wagers with Las Vegas casinos and had his business cover some of his losses.

Another card may have fallen in the governor's house of cards. Christopher Kelly -- one of Gov. Blagojevich's closest advisers, fund-raisers and friends -- is set to plead guilty in his federal criminal case, according to a court filing.

Kelly was charged last year with failing to report gambling proceeds. He was not charged with conduct related to state deals but is widely known to be under scrutiny for fund-raising schemes under Blagojevich.

A source said Kelly is not cooperating with prosecutors in the Blagojevich case.
