Business Insider GOP primary debate: on Environment

Bill Weld: I'm a lifelong environmentalist, like Theodore Roosevelt

Bill Weld: No, it is not. And the regulations that the president has rolled back are regulations dear to my heart to protect clean air & clean water in the United States. I'm a lifelong environmentalist. The Republican Party has a rich tradition in conserving our environment. Theodore Roosevelt started a national park service. It goes all the way back to Abraham Lincoln. The Clean Water Act and the Clean Air Act were enacted when Richard Nixon was president. Mr. Trump is tossing that out the window in order to do whatever might be beneficial to the coal companies. But they deserve no credit for their deregulator efforts in the environmental area. The only other regulations they really rolled back are the regs designed to protect little people in the event of another 2008 financial crisis.

Donald Trump: Don't micromanage every rain puddle and drainage ditch

President Trump: Working with Republicans in Congress, we slashed 30,000 pages of federal regulations. Government will no longer try to micromanage every rain puddle, and every drainage ditch on private land.

Q: Isn't that something Republicans should be excited about?

Bill Weld: No, it is not. And the regulations that the president has rolled back are regulations dear to my heart to protect clean air and clean water in the United States. I'm a lifelong environmentalist. The Republican Party has a rich tradition in conserving our environment.

Joe Walsh: Balance environmental regulation with small business needs

Joe Walsh: Like every issue, it's a balance between the environment and small In my Party, too many people think it's a hoax. But don't forget about those small businessmen and women all over this country who have been unduly burdened by government regulations over the years. We're trying to find the balance. Has Trump gone too far? Well, probably, [as he does] pretty much with everything.
