Nevada Assemblymember Howard Watts said in an interview that the legislative committee he chairs will “absolutely” look into pursuing an independent audit into who was responsible for altering a key public record after a Nevada OSHA inspection of Elon Musk-owned Boring Company.

Fortune reported in November that a document in Nevada OSHA’s inspection file was altered after the agency withdrew citations it had issued to the Boring Company in relation to a safety incident at one of the company’s tunneling sites. The matter was an area of questioning in a hearing on Tuesday, where state environment and safety regulators testified before the Nevada Legislature’s Interim Standing Committee on Growth and Infrastructure. A senior safety official acknowledged at the hearing that the document was altered, but said the agency had been unable to determine who had changed it.

In an interview after the hearing, Watts, a Democrat who chairs the committee, told Fortune that the Committee would look into options to pursue an independent audit and understand what happened to the altered record.

“I think it would be in the best interest of transparency and accountability to have a third party do their own forensic audit,” Watts told Fortune.
