Rep. 
Michelle Bachmann speaks to Tea Party Patriots at the Audit the IRS Rally on June 19th in Washington, DC.: 
I Was An IRS Insurgent Because Understanding The Enemy Is Best Way To Defeat Them  June 19, 2013 - Michele Bachmann at Tea Party Rally 'Audit the IRS' -  Rep. Michele Bachmann (R-MN) delivered a short speech the the Tea Party  Patriots' "Audit the IRS" rally Wednesday afternoon and used the  opportunity to defend her former career with that very same government  institution. Claiming she was an "insurgent" at the IRS, Bachmann said  she only took the job because she believes that "if you understand the  enemy from the inside out, that's the best way to defeat them."
"Well,  it's been a hundred years now that we've had the current United States  tax code," Bachmann said to the adoring crowd. "Don't you think a  century of oppression is enough?" From there she went on to tell the  story of her "former life" when she was "an insurgent" at the IRS.
"I  was an insurgent because because I absolutely wanted to defeat the tax  code and bring more liberty about in the United States," she said. "And  so after I went to law school, I got a post-doctorate degree in tax law  and after that I got a job with the IRS as a tax lawyer. Because I  believe if you understand the enemy from the inside out, that's the best  way to defeat them."
Bachmann described her colleagues in the  House of Representatives as being "more frightened of real people than  anything else." So, she said, "I think that there are shivers right now  going up of a lot of politicians in that building," she said, referring  to the U.S. Capitol behind her. "You're here and you're clear with your  message," she concluded. "And your message is, it's time to abolish the  IRS!"
During her campaign for the Republican presidential  nomination in 2011, Bachmann's four-year stint as a tax lawyer for the  IRS drew criticism from her competitors. She used similar rhetoric then  to dismiss any suggestions of hypocrisy, citing "the first rule of war":  "know your enemy."
