Despite keeping Defense Secretary Robert Gates in the Pentagon, President-elect Obama’s transition team informed 90 Bush appointees their services will not be needed after Inauguration Day.

Scott Gration, a senior official on Obama’s transition team, called and emailed several of President Bush’s Pentagon appointees about 10 days ago to inform them they were being dismissed.

Those calls and emails were followed up by an email from Jim O'Beirne, the special assistant to the secretary of defense for White House liaisons, who expressed exasperation that Gration informed the employees directly instead of letting O'Beirne's office know first.

"With regard to the process, I am unable to provide an explanation," O'Beirne wrote on Tuesday in the email, which was obtained by The Hill. "I played no part in it, and I will not speculate why matters were handled as they were."

But O'Beirne made it clear in the email that in some cases of dismissal, he thinks the employee's politics played a role in their being let go.

In the email, O'Beirne tried to assure the soon-to-be displaced employees that the decisions were based on "policy change in the Obama administration" and not based on performance.

However, he said, if employees "harbor residual doubts" then they can "content yourself with the likelihood that it was your outstanding performance as a Bush appointee that drew the opposition's attention to you."

"In that regard, you may take justifiable satisfaction that you were among the first to be chosen," O'Beirne wrote.

After the fall of Saddam Hussein's government in April 2003, the opportunity to participate in the U.S.-led effort to reconstruct Iraq attracted all manner of Americans -- restless professionals, Arabic-speaking academics, development specialists and war-zone adventurers. But before they could go to Baghdad, they had to get past Jim O'Beirne's office in the Pentagon.

To pass muster with O'Beirne, a political appointee who screens prospective political appointees for Defense Department posts, applicants didn't need to be experts in the Middle East or in post-conflict reconstruction. What seemed most important was loyalty to the Bush administration.

O'Beirne's staff posed blunt questions to some candidates about domestic politics: Did you vote for George W. Bush in 2000? Do you support the way the president is fighting the war on terror? Two people who sought jobs with the U.S. occupation authority said they were even asked their views on Roe v. Wade .

If employees “harbor residual doubts” then they can "content yourself with the likelihood that it was your outstanding performance as a Bush appointee that drew the opposition's attention to you."

Many of those chosen by O'Beirne's office to work for the Coalition Provisional Authority, which ran Iraq's government from April 2003 to June 2004, lacked vital skills and experience. A 24-year-old who had never worked in finance -- but had applied for a White House job -- was sent to reopen Baghdad's stock exchange. The daughter of a prominent neoconservative commentator and a recent graduate from an evangelical university for home-schooled children were tapped to manage Iraq's $13 billion budget, even though they didn't have a background in accounting.

The decision to send the loyal and the willing instead of the best and the brightest is now regarded by many people involved in the 3 1/2 -year effort to stabilize and rebuild Iraq as one of the Bush administration's gravest errors. Many of those selected because of their political fidelity spent their time trying to impose a conservative agenda on the postwar occupation, which sidetracked more important reconstruction efforts and squandered goodwill among the Iraqi people, according to many people who participated in the reconstruction effort.

To recruit the people he wanted, O'Beirne sought résumés from the offices of Republican congressmen, conservative think tanks and GOP activists. He discarded applications from those his staff deemed ideologically suspect, even if the applicants possessed Arabic language skills or postwar rebuilding experience.

Smith said O'Beirne once pointed to a young man's résumé and pronounced him "an ideal candidate." His chief qualification was that he had worked for the Republican Party in Florida during the presidential election recount in 2000.

"I'm not here for the Iraqis," one staffer noted to a reporter over lunch. "I'm here for George Bush."
