Whistleblower in Blago Case: Corruption 'Never Ceased to Amaze Me'

Wore a Wire in Her Bra

"For females you typically wear it in your bra. And that is where I wore it," Davis said. "Initially, I was afraid it would somehow become known that I was wearing it. Over time it became much more normal. I actually think that I became fairly good at it."

Agents wired Davis, her office and home phones, and listened to her conversations from a van in the hospital parking deck. Davis worked undercover with the FBI for about eight months. Each of her conversations about the pay to play hospital negotiations uncovered more about the web of political corruption that consumed Chicago.

"I could definitely sense a feeling of much more seriousness about the situation than when I had met with them previously in their office," Davis said, after her first time wearing a wire.

The probe into the health planning board would soon expand, exposing other allegedly corrupt political dealings in the state, and ultimately, over five years, catching references to the governor's alleged involvement in corrupt deals.

"They felt they were so smart and powerful that whatever they attempted to do was well within their control and they would never be stopped," said Davis. "The rapidity of repeating really obnoxious criminal acts and the ease with which they seemed to do it never ceased to amaze me."

Davis says civic responsibility compelled her to "do the right thing," at times sacrificing her own health and well-being.

"I found I became exceedingly secretive and isolated during this time and probably more so than I even recognized. I spent a good deal of time really in isolation to protect innocent people," Davis said.

Davis hopes that her stint as an undercover FBI informant will help change the nature of Chicago politics, putting an end to the widespread machinery systems that have propagated corruption for so long.
