Articles: Who helped Barack Obama avoid the taint of Chicago corruption?
"How did Barack Obama emerge from Chicago in 2008 untainted by political corruption?
His rise to power began at the 2004 Democratic Party Convention when Illinois State Senator Barack Obama was catapulted onto the national stage by the alluring force of his oratory.
Four years later, in December 2008, Rod Blagojevich, the fourth governor in recent Illinois history to be imprisoned, was arrested by the F.B.I. culminating a long investigation led by the U.S. Attorney (USA) in Chicago.
“Blago’s” arrest came just as he was about to meet with someone to negotiate a bribe in exchange for appointing then-U.S. Congressman Jesse Jackson, Jr. to complete President Obama’s senatorial term.
On the day Blago was arrested, the agent in charge of the Chicago F.B.I. Office said, “If [Illinois] isn’t the most corrupt state in the United States, it is certainly one hell of a competitor.”
Jackson, Co-Chair of President-Elect Obama’s campaign, was later arrested, along with his wife, and sentenced, in August 2013, to 30 months in jail for stealing $750,000 from his own campaign fund.
One year before Obama was inaugurated President, Antoin “Tony” Rezko, a key fundraiser for both Obama and Blagojevich, and one of three core members of Obama’s 2004 senatorial campaign finance committee, was arrested by F.B.I. agents acting on evidence gathered by the USA in Chicago. Three years later, Rezko was sentenced to 10.5 years in prison.
There’s no need here to rehash Rezko’s and Blago’s criminal transgressions in detail, or document the many Illinois politicians, from both major parties, who, over the years, traded their business suits for jump suits.
It is common knowledge that Chicago is the center of political corruption in a widely corrupt state.
Yet, somehow, the 44th President of the United States emerged from that toxic cauldron called “Crook County” untainted by the maelstrom of high-profile corruption cases that engulfed several of his closest, political associates.
The question is…
How did that happen?
