Watch Pete Buttigieg tour site of Ohio train derailment in East Palestine

US transport secretary Pete Buttigieg visited the site of the Ohio train derailment.

This video shows Buttigieg addressing the public at the scene where the wreck took place nearly three weeks ago.

His visit comes the day after former president Donald Trump visited East Palestine in a move branded by some as a "political stunt."

The government is facing growing criticism over the federal response to the derailment - something the Biden administration has defended against.

Initial details from the INSB investigation into the cause confirm the theory that a wheel-bearing overheated and broke.

Residents were evacuated after the derailment on 3 February and locals were concerned about potential contamination of air and water following a controlled burn of toxic chemicals aimed at preventing an explosion.

The EPA found that lab samples of local water had not been contaminated.
