This week, U.S. House members will be getting back to regular business for the first time since the January 8 Arizona shootings that killed six and wounded 13, including one of their colleagues, Rep. Gabrielle Giffords, D-Arizona. That regular business includes a vote on repealing the health care reform law.
Also in Washington, days after Secretary of State Hillary Clinton said the U.S.-China relationship is at a critical juncture, President Barack Obama will be hosting Chinese President Hu Jintao for a state visit this week.
Here's a look at these issues and some of the other stories we plan to follow this week:
Health care repeal debate to resume in Congress
House Republicans had intended to have the House vote on whether to repeal health care reform last week, but GOP leaders postponed the vote after the Arizona shootings. Debate could come Tuesday, with a vote on Wednesday.
Even if the GOP-controlled House votes for a repeal, the measure is considered to have almost no chance of surviving a Democratic-controlled Senate or a promised presidential veto.
CNN will monitor developments of Giffords' recovery and the investigation into the shootings and suspect Jared Lee Loughner. One of Giffords' friends, U.S. Sen. Kirsten Gillibrand, D-New York, said Sunday that Giffords was moving both sides of her body and was able to breathe on her own. Giffords was shot in the head. Her condition was upgraded from critical to serious on Sunday.
Chinese president, Obama to meet
Chinese President Hu Jintao arrives in Washington on Tuesday for talks later in the week with President Barack Obama. The visit comes after Secretary of State Hillary Clinton last week called on China to end discrimination against U.S. companies and to stop preferential treatment for Chinese firms. The visit also comes after a U.S. delegation that was sent to China to negotiate economic deals returned from Beijing disappointed with a lack of progress, a senior administration official said. Clinton last week noted many tensions between the two countries on economic and security issues, but she said ties were improving and that the Obama administration wanted a "positive, cooperative and comprehensive" relationship.
Tunisia set for new government after president flees
Leaders in Tunisia are expected to announce a short-term unity government on Monday after President Zine El Abidine Ben Ali fled the country amid protests. Tunisians, spurred by the suicide of an unemployed college graduate after police confiscated his fruit cart, have been protesting for days over what they consider poor living conditions, high unemployment, government corruption and repression. Ben Ali had been in charge for 23 years. Other Arab nations with a long-time president and a young, underemployed population will be watching Tunisia closely.
Lebanon starts process to choose new prime minister
Lebanon's president will start consulting Monday with members of parliament on whom to name as the new prime minister, who will then try to form a new government. Prime Minister Saad Hariri's government collapsed last week when members of the Hezbollah movement and its allies resigned their ministerial posts, in part because the government wouldn't denounce a U.N.-backed tribunal's investigation of the 2005 assassination of the premier's father. The tribunal is expected to indict members of Hezbollah, possibly this month.
Floods still threaten thousands of Brazilians
Hundreds of people already have died in flooding in a mountainous region of Brazil's Rio de Janeiro state, and thousands of other people who are living on mountain slopes or riverbanks still are at risk of being washed away.
More than 600 deaths were reported as of Sunday, but rescuers have not been able to reach some flooded areas, and many more people are feared dead. More rain is expected this week in areas that already are submerged.
More flood warnings in Australia
As Queensland state in northeastern Australia continues to come to grips with flooding that has killed at least 18 people, flood warnings have been issued to the south, in Victoria state. In Queensland, weeks of rain swelled the Brisbane River, inundating more than 20,000 homes.
Australian Open to begin after stars raise flood money
The Australian Open - the first Grand Slam tennis event of the year - kicks off in Melbourne on Monday, a day after tennis stars came together for two exhibition matches to raise money for flooding victims. The Rally for Relief took place Sunday at Rod Laver Arena, featuring Roger Federer, Rafael Nadal, Andy Murray, Caroline Wozniacki, Kim Clijsters and others.
As for the Open itself, defending champion Federer will be hoping to keep Nadal from getting his fourth straight Grand Slam title in men's singles. On the women's side, defending singles champ Serena Williams is out because of injury. Wozniacki and Clijsters are among the favorites, with Clijsters looking for her first Australian Open win and Wozniacki seeking her first Grand Slam title.
