MEXICO CITY- As he prepares to take over a country rife with violence and plagued by drug wars, Mexico's president-elect Enrique Pena Nieto is promising to focus first and foremost on making the streets of his nation safer.

Pena Nieto claimed victory after a recount scare on Wednesday. Over half of all ballot boxes were reopened and recounted amid accusations of vote buying. Following the official recount, Pena Nieto was again declared the next Mexican president.

Two days after his victory in Sunday's election, Pena Nieto told ABC News' Cecilia Vega in an interview that Mexico's war on violence can be won, but policy changes must be made.

"We have to emphasize the reduction of violence that our country lives in right now. The policy of fighting insecurity has to have social support and to achieve that goal it's necessary today to give Mexicans conditions of greater calm and security," Pena Nieto said in an interview conducted in Spanish and translated into English.

"I don't know if it's been extraordinary for the president, but it's been extraordinary for me. He gave me a life and showed me things over the past 40-some years that never in a hundred million years would I have seen or been privileged to experience," Weintraub said sitting next to the former president at Bush's home in Kennebunkport, Maine.

"The biggest thing I learned from him was to respect other Read More »from President George H.W. Bush on life and lasting friendships

Michael J. Fox, whose turn from Parkinson’s disease patient to scientific crusader made him one of the country’s most visible advocates for stem cell research, now believes the controversial therapy may not ultimately yield a cure for his disease, he told ABC’s Diane Sawyer in an exclusive interview.

There have been “problems along the way,” Fox said of stem cell studies, for which he has long advocated.   Instead, he said, new drug therapies are showing real promise and are “closer today” to providing a cure for Parkinson’s disease, a degenerative illness that over time causes the body to become rigid and the brain to shut down.

 “Stem cells are an avenue of research that we’ve pursued and continue to pursue but it’s part of a broad portfolio of things that we look at. There have been some issues with stem cells, some problems along the way,” said Fox, who suffers from the diseases’ telltale tics and tremors.

 “It’s not so much that [stem cell research has] diminished in its
