The Pentagon's internal watchdog is looking into claims by a top Army contracting official that a Halliburton Co. (search) subsidiary unfairly won no-bid contracts worth billions of dollars for support services in Iraq and the Balkans.

The complaint alleges that the award of contracts without competition to restore Iraq's oil industry and to supply and feed U.S. troops in the Balkans puts at risk "the integrity of the federal contracting program as it relates to a major defense contractor."

It also asks protection from retaliation for the whistle-blower, Bunnatine Greenhouse, chief contracting officer of the Army Corps of Engineers (search).

A letter from an Army attorney to Greenhouse's lawyer said the matter is being referred to the Defense Department's inspector general for "review and action, as appropriate." It also said the Corps had been ordered to "suspend any adverse personnel action" against Greenhouse "until a sufficient record is available to address the specific matters" in her complaint.

Copies of the letter and complaints, documents provided to some members of Congress, were obtained Sunday by The Associated Press.

Wendy Hall a spokeswoman for Houston-based Halliburton, said company subsidiary "KBR (search) doesn't have any information on what Bunny Greenhouse may or may not have said to other Pentagon officials in early 2003. Certainly, we can't address any threatened legal action she may be considering against her employer."

"On the larger issues, the old allegations have once again been recycled, this time one week before the election," Hall said.

The Iraq contract has been a focus of the presidential campaign because Vice President Dick Cheney is a former chief executive officer of Halliburton and continues to receive deferred compensation from it.

Hall emphasized that a report earlier this year by the congressional Government Accountability Office (search) concluded the Iraq contract had been properly awarded. The Balkans issue "was fully dealt with and resolved several years ago ... (and) since that time KBR has received high marks from the Army on our Balkans support contract," she added.

Greenhouse lawyer Michael D. Kohn contended in a letter to acting Army Secretary Les Brownlee (search) that in the Balkan contract a deputy assistant secretary of the Army had ordered changes in documents to legitimate the contract "for political reasons."

Kohn's complaint said contracts were approved over Greenhouse's reservations, changes were handwritten on the original contracts and extensions were awarded because underlings signed them without her knowledge and in collusion with senior officials.

After her superiors signed off on the Iraq contract and returned it for her necessary approval, the complaint said, Greenhouse wrote beside her signature: "I caution that extending this sole-source effort beyond a one-year period could convey an invalid perception that there is not strong intent for a limited competition."

The contracts under investigation grew out of a $7 billion, multiple-year award to KBR to rehabilitate Iraq's oil industry after the U.S.-led invasion last year; and an 11-month extension, which cost $165 million, of a $2 billion services contract the Army awarded in May 1999.

The Iraq contract was awarded in February 2003, less than a month before the invasion, under a clause specifying no-bid contracts in cases of "compelling emergency." The complaint said Greenhouse objected to the five-year term, asking why the certainty that the emergency would continue that long.

Kohn said Sunday he still wants an independent probe and will ask Attorney General John Ashcroft to appoint investigators to conduct their own probe to ensure the investigation is complete, independent and fair to his client.
