Trump on Thursday fired back after President Obama said world leaders are "rattled" by Trump and accused the presumptive GOP presidential nominee of being ignorant on world affairs.


"When you rattle someone, that’s good," Trump said at a press conference in Bismarck, N.D.

"Many of the countries in our world have been absolutely abusing us and taking advantage of us. ... If they’re rattled in a friendly way, that’s a good thing, not a bad thing."

The real estate mogul also lashed out at Obama, saying he has "not done a good job." 

"He shouldn't be airing what he's airing. Where he is right now — I think you're going to see it stop really soon," he said. 

"He has not done a good job," Trump added. "He's a president that's done a horrible job." 

Obama said Thursday during his trip to Japan that Trump's nomination has many world leaders concerned. 

"They're rattled by him and for good reason," Obama said.
"Because a lot of the proposals that he's made display either ignorance of world affairs or a cavalier attitude or an interest in getting tweets and headlines instead of actually thinking through what is required to keep America safe."
