Maybe Robert De Niro didn't know. Or maybe he forgot.

But when the superstar actor joked at a New York Obama campaign fundraiser Monday evening which Michelle Obama attended about the country not being ready for a white first lady, he got into dangerous territory for President Obama.

We hear a lot about juvenile offenders when they commit a crime — and again, when they're sentenced to spend the rest of their lives in prison. But not much is known about what happens after the prison gates slam shut.

The USGS says an earthquake with a magnitude of 7.4 hit southwest Mexico today.
