More than 90 heads of state are on their way to South Africa for what is expected to be the largest gathering of world leaders in Africa's history.
It's a clear sign of what kind of impact Nelson Mandela left on the world.
Mandela, the activist who spent 27 years in prison before becoming his country's first black president, died Thursday at the age of 95.
U.S. President Barack Obama left Washington for Johannesburg on Monday morning to attend the memorial service for Mandela, which will take place Tuesday in the city's soccer stadium. The 90,000 seats probably won't be enough to house the many mourners wanting to pay tribute to the great anti-apartheid leader.
A state funeral will be held Sunday in Mandela's ancestral hometown of Qunu in the Eastern Cape province.
At least 91 heads of state and 10 former heads of state have said they're going to South Africa this week, government international relations spokesman Clayson Monyela said.
The race to the South Pole is off - although the trek still continues for Prince Harry and teams of wounded veterans.
Ed Parker, the expedition director of the Virgin Money South Pole Allied Challenge, revealed Saturday that he'd made the decision to call off the competition among three teams to reach the pole after five days.
"The reason for this is entirely simple - safety, which remains the core principal of our expeditions," Parker said in a statement.
It wasn't bad weather that led to the decision, and Parker even said that "all three teams were progressing well" over the first five days. Rather, it was the fact that the mission - especially as a competition - was putting undue strain on the participants.
"It was becoming evident that there was a higher degree of stress imposed on the team members, due to unprecedented terrain on the plateau," said Parker, a former British soldier who co-founded Walking With The Wounded in 2010.
Prince Harry - himself a member of Britain's armed forces, having served in Afghanistan and elsewhere - has had a long association with this charity.
In several ways, he's been preparing for this latest mission for a long time. That includes taking part in a Walking With The Wounded expedition to the North Pole - even plunging into the Arctic Ocean's freezing waters - in 2011 before withdrawing to attend his brother William's wedding. More recently, he traveled to Iceland for training and even spent 24 hours in an industrial freezer in preparation for the South Pole race.
Yet, while Harry may be the only royal in Antarctica, he's hardly the only celebrity.
Swedish actor and "True Blood" star Alexander Skarsgard is an honorary member of the U.S. team, while Dominic West, perhaps best known for his role as McNulty in "The Wire," joins veterans wounded in combat from the Commonwealth nations of Canada and Australia.
Still, the stars - and focus of the event - are the veterans themselves. The three teams of seven participants each represent the United Kingdom, United States and the Commonwealth, which consists of several countries long affiliated with the British empire.
The plan was to trek more than 200 miles (322 kilometers) across the sparse continent, in temperatures as low as -35 degrees Celsius (-31 Fahrenheit).
And that's still the plan; it's just that they won't be racing.
The participants on Sunday are set to resuming the walk, hoping to traverse the 70 remaining miles to the South Pole "with no stress being placed on the teams ... enabling them all to do this in their own time," Parker explained.
Parker said he expects them all to reach that, by Friday or Saturday of next week, all of them will be at the finish "celebrating."
Newt Gingrich is fighting back against conservative critics who attacked the former Speaker of the House and co-host of CNN's “Crossfire” for his praise of Nelson Mandela.
After Mandela passed away Thursday, Gingrich posted a statement, praising him as "one of the greatest leaders of our lifetime."
The right-wing response was overwhelmingly reproachful.
"Such an amazing re-write of history since 1962 and 1990. Newt, I thought you of all people, a historian, would be true to who this guy really was," Mike Winkelman posted on Gingrich's Facebook page.
"This clenched-fist, murdering, gorilla warrior does not deserve respect from informed Americans," posted Trish Baehr-Schaefer.
There were several others posts, many generating dozens of "likes," and some with language unfit for publication.
But Gingrich shot back with a statement Saturday, challenging his critics to ask themselves what they would have done in Mandela's shoes.
"Some of the people who are most opposed to oppression from Washington attack Mandela when he was opposed to oppression in his own country. After years of preaching non-violence, using the political system, making his case as a defendant in court, Mandela resorted to violence against a government that was ruthless and violent in its suppression of free speech," he wrote.
He went on to compare Mandela to the Founding Fathers and the farmers who took up arms at Lexington and Concord in the Revolutionary War. He praised the former South African president for his calls for reconciliation, his Christian faith and his turn from Communism to opening South Africa up to free enterprise.
"I was very surprised by it," Gingrich said Sunday CNN's "State of the Union" about the backlash.
"Callista posted my statement on her Facebook page and was amazed at some of the intensity, some of whom came back three, four and five times, repeating how angry they were."
Gingrich continued: "Ironically, most of the things that people complained about occurred during the 27 years he was in prison."
Gingrich has a long history as a Mandela supporter. During the Reagan administration, he was among the many Republicans in Congress who pressured the president to impose sanctions on the apartheid regime.
Fellow conservative Ted Cruz faced a similar backlash this week when he posted a respectful tribute to Mandela that generated angry criticisms. No comment yet from the Texas senator on the reaction of some of his supporters.
The defense and prosecution agree on this much: Jordan Linn Graham pushed her husband of eight days, and he fell off a cliff to his death in Glacier National Park in Montana.
The question for jurors will be whether Graham's act was murder or an accident caused by self-defense.
Graham's trial is scheduled to begin with jury selection Monday in U.S. District Court in Missoula, Montana,
Cody Johnson, 25, disappeared July 7. Four days later, the FBI says, Graham led friends and relatives to a popular spot in the park, where they found Johnson's body.
The 21-year-old new bride at first maintained she had simply speculated Johnson might have gone there. But an FBI agent said that she changed her story when she was shown a surveillance photo of the couple entering the park together.
"Bottom line is eight days after you're marriage, you have surveillance photos of both of them walking into the park, he ends up dead at the bottom of a cliff and she tells no one. That's really all I need."
What exactly Graham said next to the FBI will be fiercely contested at the trial.
At a pre-trial hearing November 15, Graham testified, "We went on a little stump part and we were in the middle of an argument and he thought I was going to run away. Cody had grabbed me and I thought he was going to push me down. My first instinct was to get him off."
In a court fiilng, the defense said Graham pushed Johnson away as she removed his hand from her arm, and her husband tumbled over the cliff.
But the criminal complaint against her says that in an FBI interview, "Graham stated she could have just walked away, but due to her anger, she pushed Johnson with both hands in the back and as a result, he fell face first off the cliff."
Her attorney, federal public defender Michael Donahoe, said the FBI did not record the first hour and 20 minutes of Graham's interrogation. He accused an FBI agent of then making "an epic effort" to get Graham to use "key words" in a recorded session that would support a criminal conviction.
A defense motion says that in two subsequent recorded FBI interviews, Graham said she acted in self-defense and that her husband's fall was an accident.
Graham, who had been a part-time nanny, is accused of murder and making false statements.
The case is being prosecuted in federal court before U.S. District Judge Donald W. Molloy because the incident occurred in a national park.
