Looking up one of the names from the article in the previous post, I found W Post — Halliburton Contract Critic Loses Her Job:

Greenhouse came to prominence last year when she went public with her concerns over the volume of Iraq-related work given to Halliburton by the Corps without competition. The Houston-based oil services giant already had a competitively awarded contract to provide logistics support for the military in the Middle East and was awarded a no-bid contract to repair Iraq oil fields on the eve of the war there in 2003.

Greenhouse complained internally about that contract. Last fall she started giving interviews to national publications. And in June she testified before a Democrat-sponsored Capitol Hill event on contracting in Iraq.

“I can unequivocally state that the abuse related to contracts awarded to KBR represents the most blatant and improper abuse I have witnessed” in 20 years working on government contracts, Greenhouse said at the Democratic forum.

[...] Last October, Greenhouse has said, Maj. Gen. Robert Griffin, the Corps’ deputy commander, told her that he was demoting her, citing negative performance reviews. He also gave her the option to retire. Instead, she hired a lawyer and took her story to the public.
