Donald Trump’s son says the Obama administration’s fracking regulations on federal lands are “reasonable,” expressing little concern for rolling back the rules if his father becomes president.

“We do have to preserve those lands, and I think what I’ve seen thus far has been very reasonable,” said Donald Trump Jr., to a conservation group on Thursday. “I think we’ve worked, you know, pretty well to ensure we have the ability to … drill and frack, you know, where it makes sense and to take advantage of the, you know, the great natural resources that we have.”
