Continental Resources CEO Harold Hamm said Wednesday that presidential candidate Donald Trump did not fully understand questions posed earlier this month about local fracking bans.

The famed oil executive told the Wall Street Journal that Trump “did not understand” questions about local fracking bans that were asked by a Colorado reporter.

During an interview with Colorado’s 9NEWS Trump said that “voters should have a big say” as to whether local bans on hydraulic fracturing should be imposed.

“Some areas maybe they don’t want to have fracking. And I think if the voters are voting for it, that’s up to them.” Trump said.

When asked by 9NEWS if voters should be able to ban fracking Trump responded that, while he would need more details, “it could very well be” that voters should be allowed institute bans.

“Fracking is something that’s here whether we like it or not, but if a municipality or a state wants to ban fracking, I can understand that,” Trump added during the interview.

Hamm, who is advising Trump on energy matters, told the Wall Street Journal on Wednesday that the Republican candidate “did not understand that concept at the time in my opinion.”

Hamm told the paper that he believes Trump now understands the issue and that the candidate does not support local fracking bans or moratorium.

Trump has not commented on Hamm’s remarks.

Earlier this year, Colorado’s Supreme Court struck down two local government bans on hydraulic fracturing.

Voters in Colorado could have a chance to vote on statewide fracking restrictions this November.

Colorado’s Secretary of State is expected to decide as soon as this week if two initiatives to curb fracking in the state could land on the ballot, the Wall Street Journal said.

According to Reuters, one of the ballot initiatives calls for oil and gas development facilities to be at least 2,500 feet from occupied structures and other areas such as parks.

The other initiative would grant local governments regulatory authority over new oil and gas developments.

Petitions to include the initiatives on November’s ballot received the required number of signatures and were submitted to Colorado’s Secretary of State on Monday.
