Here's a look at the week ahead:

Cholera outbreak in Haiti

We'll be keeping an eye on Haiti, where officials are trying to contain a cholera outbreak that already has killed 253 people and sickened another 3,000. Officials in the impoverished island nation, which still is dealing with January’s devastating 7.0 magnitude earthquake, are trying to keep cholera from spreading in the capital, Port-au-Prince, where tens of thousands of people are still living in post-earthquake tent cities. As of Sunday, five cases of cholera had been confirmed in the capital.

People already are sending in iReports on the cholera outbreak. If you're in Haiti, you're invited to share your photos and video.

Trials for ex-Yankee, Florida murder suspect and Guantanamo detainee

A number of high-profile trials will begin Monday, including that of former New York Yankees player Jim Leyritz, who is accused of DUI manslaughter. Authroities say Leyritz - known in part for a dramatic three-run homer that helped the Yankees win Game 4 of the 1996 World Series - was leaving a December 2007 birthday celebration when his vehicle crashed with another, killing the second vehicle's driver, in Fort Lauderdale, Florida. Authorities say both drivers were intoxicated, but Leyritz's attorney is barred from telling the jury of the second driver's intoxication.

Also starting Monday is the trial of Leonard Patrick "Pat" Gonzalez Jr., one of the people charged with murder in the July 2009 home-invasion slayings of a Pensacola, Florida, couple known for adopting 13 special-needs children. Authorities said Byrd and Melanie Billings, who also each had two biological children, were shot multiple times, and that nine of the children were at home when the invasion happened. "We are very anxious to share this story with Escambia County and the nation. It's going to be a humdinger,” Escambia County Sheriff David Morgan said that August. Now's the time for it to all come out.

CNN.com's Justice section will carry live video of parts of the Leyritz and Gonzalez trials.

Monday also is the day that the military trial for Guantanamo Bay detainee Omar Khadr - who was 15 when he allegedly threw a grenade that killed a U.S. soldier in Afghanistan in 2002 - is scheduled to resume. Sources told CNN that he was being offered a plea deal in which he would spend some prison time in his native Canada, but as of Sunday afternoon, multiple Canadian news outlets were reporting that no deal had yet been reached. If convicted, Khadr would face a maximum life sentence.

Hurricane Richard bears down on Belize

Belize and the Yucatan Peninsula are expected to be dealing with a large amount of rain from Hurricane Richard early this week. The storm is expected to reach the Belize coast on Sunday evening. As of Sunday afternoon, forecasters were saying the storm should weaken over land and dissipate in the southwestern Gulf of Mexico, rather than redeveloping into a hurricane and threatening the U.S. Gulf Coast.

Midterm campaigning in the home stretch

This will be the last full week of campaigning before the November 2 midterm elections, which determine whether Democrats will retain control of the U.S. House and the Senate. Starting Saturday, President Obama will head to Democratic rallies in four states, including Pennsylvania and Connecticut, which have very tight Senate races and competitive gubernatorial battles.

This year's gubernatorial races take on added importance because of the 2010 census. Because of population changes, 18 states will gain or lose congressional seats, and governors, who have an impact on how congressional districts will be redrawn, are up for election in 15 of them, including Florida. On Monday, CNN will carry a debate - moderated by CNN's John King - between Florida gubernatorial candidates Alex Sink and Rick Scott.

Comedy Central's Stewart, Colbert on National Mall

"The Daily Show" host Jon Stewart will lead his "Rally to Restore Sanity" on Washington's National Mall on Saturday. The same day and place, Stewart's Comedy Central colleague Stephen Colbert will launch his "March to Keep Fear Alive." Stewart has said the events are meant to satirize the political process and media coverage of politics, rather than to respond to Glenn Beck's "Restoring Honor" event a couple of months ago.

France set to defy protesters

France's Senate and National Assembly is expected to vote this week on a final version of a bill to raise the retirement age from 60 to 62, a measure that the government says is necessary to save money. The plan sparked days of protests, with people scuffling with police and blockading oil refineries and terminals. More protests are planned.

Barnes & Noble has scheduled a news conference for Tuesday afternoon in New York City, and speculation is swirling that the bookseller is going to announce a new version of its Nook e-reader, this time with a full color screen. The editors of CNN.com's tech section will be watching.

Entertainment: 'Glee,' Nintendo and the NBA

Ahead on TV and movie screens: Fox's "Glee" will do the time warp this week with their "Rocky Horror Picture Show" themed episode, and lots of blood and gore will be expected for viewers when "Saw 3D" premieres on Friday.

Rewind to last week

That was the look ahead. Now, here's a look at some of the stories CNN covered in the past seven days:

Picture of the week: Students on Thursday take part in a demonstration in Nantes, France, as part of nationwide rallies against French government

Monday:

Osama bin Laden and his deputy Ayman al-Zawahiri are believed to be hiding close to each other in houses in northwest Pakistan, but are not together, a senior NATO official said.

Former NFL linebacker Junior Seau was arrested on a domestic violence charge in Oceanside, California, just hours before he drove his car off a cliff in nearby Carlsbad, authorities said.  Police later said that although he still faced a domestic violence charge, they wouldn't charge Seau for driving off the cliff. It appeared he fell asleep at the wheel, police said.

Tuesday:

The wife of Supreme Court Justice Clarence Thomas said that she reached out to Anita Hill, whose accusations of sexual harassment almost derailed Thomas' high court nomination 19 years ago.  Hill, a law professor at Brandeis University, turned the message over to campus security and said she had no intention of apologizing.

After police officers and construction workers heard gunshots at the Pentagon in Washington in the early morning, the building was shut down for 40 minutes as authorities conducted an interior sweep of the building. Two bullet fragments were found in windows of the building, but authorities were unsure who fired the shots.

A Saudi prince was found guilty of murdering an aide at a London hotel in February, in a case prosecutors said had a sexual element.

Wednesday:

A federal appeals panel temporarily blocked a lower court ruling that halted enforcement of the "don't ask, don't tell" policy banning openly gay and lesbian soldiers from the military. The ruling by a three-judge panel of the 9th Circuit Court of Appeals gave the government the delay it sought in challenging a federal judge's order last week to stop enforcing the policy.

Whooping cough claimed the life of a 10^th infant in California, in what health officials called the worst outbreak in 60 years.

NPR dropped Juan Williams' contract, two days after the news analyst said on Fox News' "The O'Reilly Factor" that he gets nervous when he sees people with Muslim garb on planes. Not long afterward, Fox announced it had signed Williams to an expanded role with the network in a multiple-year deal.

Thursday:

Defense Secretary Robert Gates raised the level at which gay and lesbian troops can be discharged under the "don't ask, don't tell" policy, ordering that it only be done by the secretaries of the Army, Navy and Air Force, a senior Defense Department attorney.

Thousands of people protested in Paris as France's Senate adopted rules raising the country's retirement age from 60 to 62, setting the stage for it and the National Assembly to vote on a final version this coming week.

Two U.S. air marshals who arrested the wife of a Brazilian judge on a flight to Rio de Janeiro - and were themselves arrested and had their passports confiscated by Brazilian authorities - fled the country earlier this month using alternate travel documents rather than face what they believed to be trumped-up charges, sources said.

Friday:

The whistle-blower website WikiLeaks published nearly 400,000 classified military documents from the Iraq War on Friday, calling it the largest classified military leak in history. The latest round of leaked documents provides a new picture of how many Iraqi civilians have been killed, a new window on the role that Iran has played in supporting Iraqi militants and many accounts of abuse by Iraqi's army and police, according to The New York Times, which got an early look at the documents.

Saturday:

Typhoon Megi hit China, sending hundreds of thousands fleeing as it made landfall in the southeastern province of Fujian, state media reported. About 270,000 people were evacuated, Xinhua news agency said. Meanwhile, the typhoon killed 11 people in Taiwan and left about 400 tourists stranded, and earlier in the week, Megi hit the Philippines and affected an estimated 258,800 people there, leaving thousands homeless.

Yemeni security forces launched an operation against al Qaeda, sweeping into a region of the country thought to be a haven for the terrorist group, the governing party said.

Nidal Hasan and failed Christmas bomber Umar Farouk AbdulMutallab, though Yemen is said not to be specifically targeting him in the operation.

A 26-year-old member of the U.S. national swimming team died Saturday during an open-water race in the United Arab Emirates, according to event officials.
