President-elect Donald Trump said Sunday that he doesn’t plan to wipe out President Obama’s legacy, but that he wants to improve efficiency and make government more responsive to businesses.

Mr. Trump was pressed by “Fox News Sunday” host Chris Wallace about charges he intends to take a “wrecking ball” to Mr. Obama’s accomplishments, which critics have said is obvious from some of the president-elect’s Cabinet picks.

“No, I don’t want to do that at all. I just want what’s right,” Mr. Trump said in an interview aired Sunday.

For an example, Mr. Trump pointed to the Environment Protection Agency, where his pick of Oklahoma Attorney General Scott Pruitt to run the agency sparked charges that he wants to dismantle it.

“EPA, you can’t get things approved. I mean, people are waiting in line for 15 years before they get rejected, OK? That’s why people don’t want to invest in this country,” said Mr. Trump. “So we’re going to clean it up. We’re going to speed it up and, by the way, if somebody is not doing the right thing, we’re not going to approve.”
