Smoke from California wildfires smothers parts of the state
The death toll has risen to at least 71 in Northern California's Camp Fire. About 1,000 people are reported missing. That blaze is now 50 percent contained after consuming more than 145,000 acres. Just outside of Los Angeles, the Woolsey Fire 78 percent contained after burning 98,000 acres. Now, dense smoke from those fires is smothering parts of the state with what has been described as "the dirtiest air in the world." Meg Oliver reports.
