NTSB chair suggests anyone 'speculating' about Ohio train disaster is spreading 'misinformation'

Theories about "what happened, didn’t happen, or should've happened" are harmful, official says.

An official with the Biden administration on Thursday suggested that mere speculation regarding this month's Ohio train derailment constitutes misinformation of some kind. 

Jennifer Homendy, the chair of the National Transportation Safety Board, assured Americans in a Twitter thread on Thursday evening that the NTSB is "working vigorously to understand what caused this train derailment" so "it never happens again."

Further on in the thread, Homendy claimed that "anyone speculating about what happened, didn’t happen, or should've happened is misleading a suffering community."

"PLEASE STOP SPREADING MISINFORMATION," she pleaded, citing reported theories about malfunctions in the train's electronically controlled pneumatic brake system. 

"I urge you: let the NTSB lead the [safety] analysis," Homendy wrote, claiming: "Anything else is harmful — and adding pain to a community that’s been through enough."
