Obama: Trump not qualified, says public should follow up on his 'wacky ideas'

U.S. President Barack Obama further reaffirmed his commitment Thursday that Donald Trump would be unsuitable for the White House and said the Republican presidential candidate has made contradictory statements.

"I don't think the guy is qualified to be president of the United States and every time he speaks that opinion is confirmed," Obama said at the conclusion of the Asian Summit in Laos.

"The most important thing for the public and the press is to just listen to what he says and follow up and ask questions on what he says, which appear to be either contradictory or uninformed or outright wacky ideas."

He added that the election season in the U.S. has somehow made behavior seem acceptable that would usually be considered completely unacceptable.

"This is serious business, you have to know what you're talking about and you have to have done your homework," Obama added.

He said that if U.S. voters really listened to what Trump had to say, then he was confident that people would make a good decision at the November elections.

Meanwhile on Wednesday, Trump once again praised Russian President Vladimir Putin, saying he has been a better leader than Obama.

"(Putin) has very strong control over a country. Now, it's a very different system and I don't happen to like that system. But certainly in that system he's been a leader far more than our president has been a leader," the Republican presidential nominee said at NBC's commander-in-chief forum in New York.
