"It's not a circumstance where I'd judge anybody," he said. "I trust that the party will give the Palin family their support."

He did applaud the daughter's decision to carry the baby and marry the father.

"Unfortunately, we have this problem all over the country," Herbert said. "It too often gets compounded by abortion."

Utah Senate Majority Leader Curt Bramble, R-Provo, said personal challenges happen to every family, and should never be used against the parents politically.

"Kids sometimes make bad decisions in good families," he said.

Palin had told McCain's team about the pregnancy and her husband's old DUI during lengthy discussions about her background, aides said. At several points, McCain's team warned Palin that the scrutiny into her private life would be intense and there was nothing she could do to prepare for it.

Shortly after her announcement, McCain's team dispatched a dozen operatives and lawyers to Alaska, fueling speculation that a comprehensive examination of Palin's past was incomplete and being done only after she was placed on the ticket. Culvahouse denied that, saying his team of 25 scoured public and private records to produce a 40-page, single-spaced report on each top candidate.

He didn't say how many candidates, nor who else made McCain's short list. Culvahouse did say Palin underwent a "full and complete" review.

Prominent religious conservatives, many of whom have been lukewarm toward McCain's candidacy, predicted that the pregnancy announcement would not diminish conservative Christian enthusiasm for the vice presidential hopeful, a staunch abortion opponent. In fact, there was talk that it might help.

"Being a Christian does not mean you're perfect," said Focus on the Family founder James Dobson. "Nor does it mean your children are perfect. But it does mean there is forgiveness and restoration when we confess our imperfections to the Lord."

As for the Alaska probe, a Republican-dominated legislative committee is investigating whether Palin dismissed Public Safety Commissioner Walt Monegan after he refused to fire a state trooper who had divorced Palin's sister.

The state's attorney general, Talis Colberg, hired Thomas V. Van Flein more than two weeks ago to represent Palin and members of her staff, according to Van Flein. He has represented the Palin family in the past as a private attorney, according to a McCain aide who spoke on condition of anonymity because he was not authorized to discuss the matter publicly.

Van Flein said he couldn't confirm representing the family because of attorney-client privilege.

"Did I know the Palins before the state hired me? Yes," he told The Associated Press.
