WASHINGTON (CNN) – The new mammogram recommendations out earlier this week caused quite an uproar. Now comes another change in screening tests for women - this one for cervical cancer.

The American College of Obstetricians and Gynecologists (ACOG) releases new guidelines Friday, saying women don't need their first cervical cancer screening - or Pap test - until they're 21 years old. And, they don't need followup examinations as often as previously recommended.

According to the guidelines, women younger than 30 should be screened every two years, instead of annually. Women 30 or older can be examined once every three years.

"The tradition of doing a Pap test every year has not been supported by recent scientific evidence," said Dr. Alan G. Waxman, who developed the document for ACOG's Committee on Practice Bulletins-Gynecology. "A review of the evidence to date shows that screening at less frequent intervals prevents cervical cancer just as well, has decreased costs, and avoids unnecessary interventions that could be harmful."

The current guidelines, from 2003, recommend that women get a Pap test three years after they begin having sexual intercourse, but no later than age 21. And that women younger than 30 have an annual exam. For women 30 or older, the recommendation was every two to three years, if they'd had three consecutive negative Pap tests.

On Thursday the Senate's Homeland Security Committee held the first public hearing on the Fort Hood shootings, which several senators called a "terrorist" attack.

Brian Jenkins was among those who testified. He's a terrorism analyst and senior adviser for the RAND corporation. He spoke to John Roberts on CNN's "American Morning" Friday.

As the Fort Hood investigation unfolds, officials are taking a much harder look at a radical imam from Yemen.

The feds think his teachings likely influenced suspect Maj. Nidal Hasan and several other jihadists accused of attacks across the globe. CNN's Jim Acosta reports.

Tim McGraw, sans trademark cowboy hat, saunters into a Manhattan restaurant and needs to find a place to throw out his gum. Finding none, he finds a clean and shiny teaspoon at a waiter station and neatly tucks his chewed gum into it. As far as I know, no one put it on eBay.

Thus begins our 35-minute sit-down with the country music star, who has a new movie, new album, a tour starting in February, and new management.

McGraw is a country music star who is bent on a “fresh start.” He’s honing his brand for a new dynamic audience. His die-hard country music fans are most-likely to buy his records from Target.

But there is a new, digitally savvy audience online, sampling tracks from various artists and genres. He has signed with Red Light Management, the people behind Dave Mathews Band and Phish, and the tour for his album Southern Voice, will be “different” from anything we’ve ever seen from him.

Has Brand McGraw set the “reset button?”

“I don't know whether it's a reset button as much as it is just an advancement button. It's just time to take this up. We've laid a tremendous platform and it is time to expand from that platform. “

That platform is 40 million country records, three Grammy awards, 10 American Music Awards, 11 Country Music Awards. You get the picture. Where he is expanding most visibly is in movies.

He co-stars opposite Sandra Bullock in "The Blind Side," opening nationwide this weekend. It’s his biggest role yet. On the red carpet at the premiere this week, Bullock told CNN about her country music co-star.

Editor's Note: Attorney General Eric Holder’s appearance on Wednesday before the Senate Judiciary Committee generated strong opinion and questions for Thursday’s "American Morning" audience. While the majority supported a trial in New York City at the federal court level, some wondered if alternative courts would be more appropriate.

• Bill: I don’t believe the terrorist should be tried in NYC. Are we going to try every one we capture in the U.S. Why should the tax payers have to pay for this trial. We have been hurt enough already. Holder is an idiot.
• Sue: Regarding trying terrorists in civilian court. I am a mental health professional and believe that trying the terrorists in New York would stimulate an adverse response for those who suffer from PTSD related to Twin Tower Attacks. No terrorist should be afforded the rights of an American to be tried by a jury of their peers. If that were the case you would have to round up peers (terrorists) in order for him to get a "fair" trial. Let the military handle this, they are much better equipped to do so!
• Mark: Why can't we ask the World Court at the Hague to hold a trial for the terrorists? Do they do that anymore? Wasn't 9/11 a crime against all humanity?
• David: If the trial of the sheik is done in either court system and he is found guilty with the death penalty, where would he be housed while all the appeals are used, which more than likely would take years? I also understand that the military has not executed anyone in years. So where is the justice?
• Lee: Why is no one talking about the right of the terrorists to a speedy trial? I am sure any defense attorney will file a motion to dismiss based on the denial of a speedy trial. Why would that motion not succeed?

What is your opinion on where the trial of the accused 9/11 conspirators should be held?

It's been three months since three Americans – Shane Bauer, Sarah Shourd, and Josh Fattal – were arrested in Iran. They reportedly crossed an unmarked border while hiking in Northern Iraq and are being held in Tehran where government officials say they now face espionage charges.

The families say it was an innocent mistake and in his first television interview, Shon Meckfessel – the "fourth" hiker, who was not arrested – told CNN's Kiran Chetry what they were all doing there in the first place.
