Donald Trump exploiting people's fears: President Barack Obama

In his first major comments on Republican presidential frontrunner Donald Trump, US President Barack Obama on Monday said that the real estate tycoon is exploiting people's fear amid a stagnant and rapidly changing economy.

"I think somebody like Mr Trump is taking advantage of that. That's what he's exploiting during the course of his campaign," Obama told National Public Radio (NPR) in an interview.

"When one combines the demographic change with all the economic stresses that people have been going through because of the financial crisis, because of technology, because of globalization, it means that there is going to be potential anger, frustration and fear," said the president.
