WASHINGTON — Ivy Leaguers and other top law students were rejected for plum Justice Department jobs two years ago because of their liberal leanings or objections to Bush administration politics, a government report concluded yesterday.

In one case, a Harvard Law student was passed over after criticizing the nomination of Samuel Alito to the Supreme Court. In another, a Georgetown University student who had previously worked for a Democratic senator and congressman didn’t make the cut.

Even senior Justice officials flinched at what appeared to be hiring decisions based — improperly and illegally — on politics, according to the internal report.

“Individuals at the department were rejecting any of our candidates who could be construed as left-wing or who were perceived, based on their appearances and resumes and so forth, as being more liberal,” the deputy director of the department’s executive office of immigration review, Kevin Ohlson, said to investigators.

The report marked the culmination of a yearlong investigation by Justice’s inspector general and Office of Professional Responsibility into whether Republican politics were driving hiring polices at the once fiercely independent department.

The investigation is one of several that examine accusations of White House political meddling within the Justice Department. Those accusations were initially driven by the firings of nine U.S. attorneys in late 2006 and culminated with the ouster of Attorney General Gonzales last September.

The report issued yesterday concluded that politics and ideology disqualified a significant number of newly graduated lawyers and summer interns seeking coveted Justice jobs in 2006.

As early as 2002, career Justice employees complained to department officials that Bush administration political appointees had largely taken over the hiring process for summer interns and so-called Honors Program jobs for newly graduated law students.
