Summer heat getting hotter

The summer heat is getting intense, so hot that forecasters put nearly 100 million Americans under excessive-heat warnings or advisories this week. The National Weather Service says the "dangerous heat" is forecast to impact a large swath of the country, including Texas, Louisiana, Kansas and Missouri. A number of states were also placed under a heat advisory with most areas forecast to reach at least the high 90s. Amarillo, Texas, is expected to reach a high of 113 degrees, and Shreveport, Louisiana, will soar to 108 degrees. Here's what we know and some tips for staying cool.

Border-control tactics contributed to inaction during Uvalde, experts say

Robb Elementary students were used to school lockdowns. But when a lockdown alert came on May 24 — the day a shooter killed 19 students and two teachers — many initially assumed it was like the 47 other lockdowns that happened, a newly released report by the Texas House of Representatives concluded.
