LOS ANGELES, California (CNN) -- The Los Angeles Coroner's chief investigator revisited the office of Michael Jackson's dermatologist Wednesday, even though the coroner announced last week his "thorough and comprehensive" report was completed.

Dr. Arnold Klein denied in a CNN interview last month that he had given Jackson dangerous drugs.

"We wanted some additional information, and they provided it," Ed Winter said as he emerged 90 minutes after entering Dr. Arnold Klein's Beverly Hills, California, dermatology clinic.

Winter, who also visited Klein's office on July 14, said the doctor's staff and lawyers cooperated with his requests.

Garo Ghazarian, one of Klein's two lawyers on the scene, said the doctor did not meet with Winter.

"They had inquiries born out of information they wanted to corroborate," Ghazarian said.

Ghazarian said he was added to Klein's legal team "to take a look and see if there's any cause for concern in light of media reports" that investigators were considering criminal charges against him.

"I have seen no cause for concern on behalf of my client, Dr. Arnold Klein," Ghazarian said.

The coroner's office said more than a week ago that a "thorough and comprehensive" report into the death of Michael Jackson is complete, but police have requested that the report not be released yet because of the ongoing criminal investigation.

The coroner's office said it would abide by the request that "the cause and manner of death remain confidential," and referred all questions to the Los Angeles Police Department.

(CNN) -- Two former presidents reflected on their greatest regrets in office Monday, each looking back to issues that continue to plague the nation years later.

Former presidents and political rivals Bill Clinton and George H.W. Bush now share philanthropic efforts.

Former Presidents George H.W. Bush and Bill Clinton appeared together at a question-and-answer forum before the National Automobile Dealers Association in New Orleans, Louisiana.

Asked his biggest regret after leaving office, Bush said he now wonders whether he should have tried to get Saddam Hussein to leave office at the end of the first Gulf War in 1991.

He told the gathering, "I've thought a lot about it, but at the end of Desert Storm, the question was should we have kind of kept going on that road to death and all this slaughter until Saddam Hussein showed up and laid his sword on the table, surrendered. And the common wisdom was he wouldn't do that."

But he said a conversation with an FBI agent who interrogated Saddam after he was captured has made him reconsider.

Bush recalled their talk, "I said, 'What if we just say he has to come to surrender, would he have done it?' And this guy said, 'I'm absolutely convinced he would have.' My experts tell me he wouldn't have."

Bush said, "We ended it the way we said we would" as a military success, but noted a cleaner ending "would have been perfect."

He added, "If we had tried to get Saddam Hussein to come and literally surrender and put his sword on the table, I think it might have been avoided some of the problems that we did have in the future from him." What are the answers to this following set of questions: 1. How many presidents are working together?

4. For what organization?
5. When?

John was a very naughty boy. He liked playing tricks on people. Sometimes he would call Mrs. Walker at the hat store and roar at her on the phone. Sometimes he would leave his wet blanket on the sidewalk so that it would squish under people's feet when they walked past. Sometimes he would moo at his sister, June, to annoy her. One time he even painted his friend Jack's bedroom purple without asking.

This upset Jack very much. Jack did not want his bedroom to be purple. Jack liked his bedroom blue and white, like his favorite sport's team. Whenever Jack was sad his dog, Scamp, was also sad. John's naughty actions really hurt Jack's feelings so he tried to hide from John. John found Jack anyway.
