Hillary Clinton and Donald Trump exchanged another round of accusations Thursday as the Republican candidate for president continues to repeat his inaccurate claim that he opposed the war in Iraq from the beginning. Josh Robin filed the following report.

Billed to speak about schools, the Republican candidate for president first turned to foreign affairs.

"Hillary Clinton is trigger-happy. Totally trigger-happy," Donald Trump said.

The charge is based on Clinton's support for the 2003 invasion of Iraq. Senator from New York then, she now says she regrets it.

"Iraq is one of the biggest differences in this race," Trump said. "I opposed going in, and I did oppose it."

In fact, he didn't, at least not in one interview less than a month before Clinton voted yes.

Howard Stern: Are you for invading Iraq?
Trump: Yeah, I guess so. I wish the first time it was done correctly.

In Libya, Trump the candidate has said it would be better if Muammar al-Qaddafi weren't deposed. As his YouTube page still shows, in 2011, he had a different take.

"We should go in. We should stop this guy, which would be very easy and very quick," Trump said at the time.

But it was Trump's comments on another country that has Clinton - and President Barack Obama, in Asia - talking. 

On Wednesday, Trump said Russian President Vladimir Putin has been far more of a leader than Obama.

"That is not just unpatriotic. It is not just insulting to the office and the man who holds the office. It is scary. It is dangerous," Clinton said.

"I have confidence that if, in fact, people just listen to what he has to say and look at his track record, or lack thereof, that they'll make a good decision."

The president is expected to increase his time on the trail stumping for Clinton. His approval ratings could help. They're far higher than hers. 

Polls show a narrowing Clinton-Trump race with two months remaining.

Meanwhile, Libertarian candidate Gary Johnson had something of an oops moment Thursday when asked about a major conflict zone.

Johnson: And what is Aleppo?
Q: You're kidding.
Johnson: No.

In a statement, the former New Mexico governor says the slip-up shows he's only human.
