How Did Michelle Obama Escape Indictment For Fraud And Corruption?

2002: Michelle Obama is hired by the University of Chicago Hospital as its “Executive Director for Community Affairs” at a salary of $120,000.
2005: Obama is sworn in as a U.S. Senator. Michelle is promoted to “Vice President for Community and External Affairs” and her salary bumped nearly $200,000 (from $121,910 to $316,962). This position was “newly created” for Mrs. Obama.
That’s not a bad increase in pay, but I don’t see the “tie” between her salary being TRIPLED and Barack Obama being sworn in as a Senator do you? I’m betting it was probably just a coincidence. It’s pretty common for state universities to triple the salaries of their employees (sarcasm).
She was responsible for the medical center’s “business diversity program” that involved relationships between the medical center and the community. External affairs? Business diversity? What exactly does this mean? How does this benefit patients? Relationships between the Hospital and the community It’s a state-run hospital. This is a B.S. position made to order. Who dreams these “pretend” jobs up?
2006: Barack Obama requests a $1 million earmark for a new hospital pavilion at the University of Chicago. Again I’m wondering if there is a tie in to Michelle Obama being an employee and her raise or if this isn’t just another convenient coincidence?
2009: Michelle Obama resigns her position at UCH. Her VP position is eliminated and its functions absorbed into another executive’s position. Question: if that work can be folded into another, why was it separate in the first place?
