Rod Blagojevich's former chief of staff John Harris reports to the McHenry County jail today to begin a ten-day sentence. 

Harris took part in Blagojevich's schemes to benefit personally from his official actions as governor.

Harris' sentence is the shortest ever for a corruption conviction; it reflects the help he gave federal prosecutors in convicting his ex-boss.

Blagojevich is serving 14 years in a federal prison in Colorado.
