The Justice Department said Tuesday it could seek more than $5 billion in damages from Standard & Poor's, the nation's biggest credit ratings company, a day after it sued the company, alleging that S&P defrauded investors by giving triple-A ratings to risky subprime mortgage investments.

In Washington, everything seems to break down along partisan lines. Gun ownership is no exception.

USA Today surveyed every congressional office to ask whether its lawmaker owned a gun.

The results?

In Washington, there's always one kind of alleged war or another against some group or idea — the war on women, the war on religion and the war on the Second Amendment come quickly to mind.

This week, many of us became aware of another supposed conflict we had never heard of: essentially, a war on Wi-Fi.

Bulgarian authorities say they have evidence the Lebanese militant group Hezbollah financed and carried out a bomb attack at a Black Sea resort town last year, killing five Israeli tourists and one Bulgarian citizen.

Bulgarian Foreign Minister Nikolay Mladenov said it was an extremely intensive investigation.

"The results of that investigation leads to a number of persons who are connected to the military wing of Hezbollah," he said.

President Mahmoud Ahmadinejad on Tuesday became the first Iranian leader to visit Egypt since the 1970s, the latest sign of the thawing of relations between the rival Muslim nations.

Ahmadinejad received a red-carpet welcome as Egypt's President Mohammed Morsi greeted him on the tarmac at Cairo International Airport with a kiss on each cheek.

Under Egypt's former leader, Hosni Mubarak, a visit like this would never have happened.

Our friends at On Point had a fascinating discussion today with the author of a new book about ninjas.

While a path to citizenship is a central component of proposed changes to the nation's immigration laws, most Mexican immigrants now eligible for U.S. citizenship don't obtain it, according to a new study.

The Pew Hispanic Center report found that only about 36 percent of eligible Mexicans take the steps to become U.S. citizens, compared to 68 percent of all other immigrants.

Although federal data show that fewer Medicare beneficiaries are dying in hospitals that doesn't mean they're getting a lot less medical care in their final days, new research suggests.

Even as deaths in acute-care hospitals declined between 2000 and 2009, the use of intensive care units in the final 30 days of life increased, as did short-term hospice use. The rate of changes to care for these patients, such as transfers within the last three days of life, also increased.
