 This is CBS News on the Hour, sponsored by O'Reilly Auto Parts. I'm Matt Piper. Records are being shattered in the West with tens of millions of people under heat alerts and advisories. One person riding on a motorcycle died in Death Valley, which hit 128 degrees today. CBS's Carter Evans. It was a group of six motorcyclists, and they were all riding through Death Valley there, and it's extremely hot. I mean, this is the day when they've got those record temperatures.
