PORTSMOUTH, N.H. — At a campaign rally Saturday, Donald Trump expressed concern about college tuition costs and the swift growth of student loan debt in the United States but offered no specifics on what he would do about it.

"It's one of the biggest questions I've had from young people," the Republican presidential front-runner told a student in the crowd who asked the billionaire to share his solution to the issue prioritized by many young voters.

Trump, who's shared very little on how we would tackle the worsening crisis, stumbled through his answer. He criticized the federal government's meddling in higher education and promised to create more jobs.

"I often tell my supporters I'll be the greatest jobs president that God ever created," he said.

He also railed against reckless borrowing.

"Students go out and they borrow money from the federal government and the colleges keep going up, up, up, much more than they should be," Trump said. "There's no incentive for the colleges to bring the costs down."

But Trump has yet to explain how he would create such an incentive.

In fact, less than two months ago,the businessman split from the maintstream conservative approach and told students the "only way" to make college affordable is to get government further involved.

"The only way you can do it is you have to start some governmental program and you have governmental programs right now," Trump said at an Iowa town hall, as previously reported by the Washington Examiner.

Some candidates have championed alternatives to federally-funded student loans such as income-sharing agreements, promised to abolish the Department of Education or called for changes to the accreditation standards. Trump has simply asked Americans to trust him.

"I'm going to solve the problem, okay?" he told the young woman in the audience Saturday.
