Federal regulators are fining Fiat Chrysler $105 million for failing to acknowledge and address safety defects in a timely fashion.

The civil penalty — the largest ever imposed by the National Highway Traffic Safety Administration — will be accompanied by three years of "unprecedented" federal oversight, the agency says. Fiat Chrysler has also agreed to buy back some vehicles from their owners.

Nearly 500 people were injured at a water park in Taiwan after an explosion at a music event caused a fire to break out Saturday night.

The fire started during an evening rap performance in New Taipei City, NPR's Frank Langfitt, reporting from Shanghai, tells our Newscast unit. The accident at Formosa Fun Coast was caught on cellphone video.

"At one point, green powder shot out from the stage over the audience," Frank says. "The powder quickly ignited, enveloping fans. Some people staggered around on fire, while others collapsed to the ground."

It took nearly four decades, but a horse has once again attained the honor that some call the most difficult achievement in sports: American Pharoah, after winning the Kentucky Derby and the Preakness Stakes, ran to victory in the Belmont Stakes as well.

He's the first Triple Crown winner since 1978. With his win, a total of 12 horses have now achieved the feat.

American Pharoah took the lead early in the mile-and-a-half long race, with Frosted close on his tail. From there, the colt never gave up the front position.

Amtrak will be restoring rail service between Philadelphia and New York at 5:30 Monday morning, the rail service announced Sunday.

Service between the two cities had been shut down since Tuesday, when train 188 derailed in Philadelphia, killing eight and wounding more than 200.

The affected section of track is part of the Northeast Corridor — the busiest railroad in America.

American Pharoah is the king of the nation's horse races this month: in a driving rain, the Kentucky Derby winner took home top prize at the Preakness Stakes Saturday.

Ridden by Victor Espinoza, he left the other horses at Pimlico Race Course eating his mud; with an unofficial time of 1:58.46, he led by an impressive seven lengths.

If he can win the Belmont Stakes on June 6, he'll be the first Triple Crown winner since 1978.

When it comes to the perfect holiday sweater, for many people, cheesy is good — tacky is better — and astonishingly ugly is best of all.

The demand for ugly holiday sweaters has reached such a height that it's changed how businesses stock for the season, as Eleanor Klibanoff reported for us on Weekend Edition Saturday. Wal-Mart and Kohl's sell new "vintage" ugly sweaters, and actual vintage stores have had to start searching for new stock to sell.
