Not everyone gets a break over the weekend. Just ask congressional leaders and President Obama, who continued talks Saturday over a possible deficit reduction that would clear the way for Republican-backed increase in the federal debt ceiling.
Rupert Murdoch also had quite the weekend as the widening phone-hacking scandal that brought down his cornerstone newspaper claimed more victims.
Here's a look at those stories, which will continue to develop this week, along with others that CNN plans to follow:
Changes in command take effect in Afghanistan
Army Gen. David H. Petraeus, current commander of U.S. and NATO forces in Afghanistan, will turn over command Monday to Marine Lt. Gen. John R. Allen. Petraeus will Â assume his new role as director of the CIA in September, replacing Leon E. Panetta, who took office as secretary of defense July 1.
The succession comes two days before the Afghan National Army takes control Wednesday of Lashkar Gah - the capital of the volatile Helmand province - in the first transfer of security from NATO-led forces. The transfer is part of a phased handover which will see all foreign troops leave Afghanistan by the end of 2014.
Space shuttle Atlantis returns to Earth for last time
The NASA space shuttle Atlantis crew will bid farewell to the international space station crew Monday before starting its return to Earth. Atlantis is scheduled to land Thursday at Kennedy Space Center - that last mission before all three space shuttles retire for good.
The return comes the day after the 42nd anniversary of the first manned moon landing in 1969.
New federal watchdog bureau opens for business
President Barack Obama on Monday will nominate Richard Cordray to head the new Consumer Financial Protection Bureau, which is scheduled to formally open for business Thursday. The announcement means Obama has passed over Elizabeth Warren, the firebrand law professor who envisioned the bureau.
The bureau was the brainchild of Warren, a former law professor, who envisioned it as a government force to protect consumers from increasingly sophisticated financial practices. The bureau is intended to make basic financial practices such as taking out a mortgage or loan more clear and transparent while ferreting out unfair lending practices.
Nelson Mandela turns 93
The United Nations and the Nelson Mandela Foundation want you to join them in commemorating Mandela's 93rd birthday on Monday by devoting 67 minutes to helping others - one minute for every year of the South African leaderâ€™s own service to humanity.
Nelson Mandela International Day falls each year on the human rights leader's birthday on July 18. It began in 2008 in recognition of the former South African Presidentâ€™s contribution to the culture of peace and freedom.
Rupert Murdoch to appear before British lawmakers
Media baron Rupert Murdoch and his son, James, are scheduled to appear before British politicians Tuesday to answer questions over the widening phone-hacking scandal plaguing his media empire.
British lawmakers investigating the scandal asked Murdoch, his son and former News of the World editor Rebekah Brooks to testify at a House of Commons hearing after former British Prime Minister Gordon Brown accused their newspaper group of illegally obtaining private information about him.
Brooks, who resigned Friday as chief executive at News International, the British arm of Murdoch's News Corp., had also agreed to testify. It's not clear how her arrest Sunday will affect the hearing.
Debt talks continue
Senate leaders are working on a possible debt ceiling measure, based on a plan that Senate Minority Leader Mitch McConnell, R-Kentucky, unveiled last week. That plan would give Obama power to raise the borrowing limit by a total of $2.5 trillion but also require three congressional votes on the issue before the 2012 general election.
According to Senate aides from both parties, a revised version of the McConnell plan being put together with Senate Majority Leader Harry Reid, D-Nevada, could come up for consideration this week, but only after legislators vote on Republican measures calling for spending cuts, caps on future spending and a balanced budget amendment to the Constitution.
Presidential candidates debate in 140 words
TheTeaParty.net, an Internet-based tea party group, will hold the first presidential debate of the 2012 campaign on Twitter on Wednesday. Republican candidates will answer questions via Twitter's requisite restriction that encourages short answers: 140 characters or less.
Minnesota Rep. Michele Bachmann, businessman Herman Cain, former House Speaker Newt Gingrich, Michigan Rep. Thad McCotter, former Minnesota Gov. Tim Pawlenty and former Pennsylvania Sen. Rick Santorum are scheduled to participate, among others, the debate's organizers said earlier this month.
Comic Con 2011 begins

More than 125,00 visitors are expected to attend for a chance to meet their favorite artists and writers, catch sneak previews of upcoming films and discussion panels.
