Children who live in areas with bad air pollution are more likely to develop asthma, which is the most common chronic illness among young people. But when you clean up the air does that actually protect the health of kids?

Know a young driver who's ignoring your pleas to buckle up? Chevrolet suggests you might try to see if they'll listen to a different authority figure: their car.

The automaker is introducing a feature, specifically for teen drivers, that will temporarily block the auto from shifting into gear if their seat belt isn't buckled. A message will alert the driver to buckle their seat belt in order to shift into gear.

After 20 seconds, the vehicle will operate normally.

In December, 33-year old Ryan Rust was found dead in his solitary cell at Alabama's Holman prison, a belt around his neck with one end tied to a bar in the cell window.

The U.S. Department of Justice has put the state of Alabama on notice to fix dangerous and deadly prison conditions or face a lawsuit that could result in a federal takeover of the prison system.

As Democratic Rep. Ilhan Omar of Minnesota was wrapping up her remarks to the crowd at a Ramadan gathering on Capitol Hill late Monday, she spotted a familiar face in the front row.

It was Khizr Khan, the Gold Star father who was famously mocked by then-candidate Donald Trump during the 2016 race. Omar told the audience she remembered how Trump had belittled Khan's wife by saying he wasn't sure if Muslim women were allowed to speak.
