ABC's George Stephanopoulos on Sunday finally asked Donald Trump what many in the media have been wondering: Where's the beef? The Republican Party presidential front-runner and former real estate baron talks a big game about crushing illegal immigration, for example, but has yet to offer his policy proposal for getting it done.

Trump's answer, in a nutshell: "Don't worry about it."

Stephanopoulos, the host of "This Week," began the interview with a direct question about the price tag of Trump's immigration overhaul -- and wasn't satisfied with the first answer.

"But let me press you on the cost right there, Mr. Trump," Stephanopoulos interrupted. "How much is it going to cost and where are we going to get the money?"

Trump gave the host the runaround for a few more minutes until Stephanopoulos forced him to reckon with the question.

"George, it's called management," Trump said.

"You keep declaring you're going to do it but you don't say how!" Stephanopoulos shot back. 

"George, I'm telling you, it's called management," Trump repeated.

"I still don't hear specifics about how you're going to do this," the host pushed on.

"My specifics are very simple. I'm gonna get great people who know what they're doing. Not a bunch of political hacks that have no idea what they're doing, appointed by President Obama, who doesn't have a clue," Trump said.

Stephanopoulos gave Trump one last shot before moving on.

"George, don't worry about it. It's called good management, and it's called great people."

The latest Economist/YouGov poll shows Trump leading the GOP pack with 25 percent of the vote as of Aug. 18. Former neurosurgeon Ben Carson trails Trump with 11 percent.
