Transportation Secretary Pete Buttigieg tweeted Monday evening that Federal Railroad Administration (FRA) staff are en route to the deadly Amtrak train derailment in Missouri to support the investigation.
Buttigieg tweeted, "Saddened by the tragic loss of life and injuries in the Missouri train derailment today & Northern California collision over the weekend."
He said he has been kept updated and his team is in touch with Amtrak & relevant authorities.
The FRA is an agency within the US Department of Transportation.
