Oil tycoon Harold Hamm on Tuesday told The Wall Street Journal that Trump’s recent comment endorsing “local control” of fracking policy stemmed from a misunderstanding of the issue.

“Donald Trump did not understand that concept at the time in my opinion,” Hamm, head of Continental Resources Inc., said at a conference in Denver. “He does now."

Trump’s comments regarding local bans came last month in a television interview in Denver. A reporter asked Trump whether he supports “local control” and the unsuccessful efforts of some Colorado towns to prohibit fracking.

“Well, I’m in favor of fracking, but I think that voters should have a big say in it,” Trump said. “If a municipality or state wants to ban fracking, I can understand it.”

The comment confused and worried the oil and gas industry, which sees local bans as a way to shut down drilling and a nuisance for their operations.

Hamm, who was also the lead energy adviser to 2012 GOP presidential nominee Mitt Romney, said he did not speak with Trump about the fracking comments, but he is nonetheless confident that Trump supports the oil and natural gas industry’s position that towns and cities should not be able to ban fracking.

“I think he was pulled into that with the term local control, which is a magnet for Republican thoughts,” Hamm told the Journal.

“Donald Trump is pro-business. He is pro-energy and he is not going to shut down fracking or drilling or anything else,” Hamm said in a speech at the conference. “He is for this industry 100 percent.”
