In this week’s FOIA round-up, emails show Texas declined National Aeronautics and Space Administration’s offer to test for air pollution following Hurricane Harvey, a Missouri senator, fresh out of an election violation investigation, is now back under scrutiny thanks to newly released communications, and now-public data shows that self-driving cars aren’t as safe as regulators claim.

After flooding from Hurricane Harvey caused chemical fires at the Arkema Chemical Plant in Crosby, Texas local officials tried to downplay the explosions, as well as the noxious nature of the plume of smoke coming from the facility - even after ten deputies were sent to the hospital after inhaling it.

We’ve filed requests with privately-run prisons and immigration detention centers in Harvey’s path to find out how they weathered the storm.
