US Democratic presidential candidate Hillary Clinton says her campaign has evidence that presumptive Republican nominee Donald Trump supported the 2003 Iraq war.
"Well, he supported it. We have evidence and audio of him supporting it. So I think that's another example of him trying to rewrite history," Clinton said on CNN's "State of the Union" program broadcast on Sunday.
Trump has said that he opposed the Iraq war before the US-led invasion, asserting he knew it would lead to destabilization of the Middle East region and creation of terrorist groups.
Trump has censured Clinton for her support of the Iraq invasion, and said that the former secretary of state should apologize to the victims of the Iraq war, which she voted in favor of as a senator.
Clinton said on Sunday that "it was a mistake" to vote for the war.
“But I said, look, it was a mistake to vote for that. But I have a lot more experience as a senator, as secretary of state, that I am more than happy to talk about throughout this campaign, because, when people vote, they are voting for the president, who is our commander in chief,” she said.
“And I have said -- and I believe this with all my heart -- he is not qualified to be commander in chief, either by experience, preparation or temperament,” Clinton added.
In March 2003, the United States and Britain invaded Iraq in blatant violation of international law and under the pretext of finding Weapons of Mass Destruction; but no such weapons were ever discovered in Iraq.
More than one million Iraqis were killed as the result of the US-led invasion, and subsequent occupation of the country, according to the California-based investigative organization Project Censored.
Trump's campaign has been marked by controversial statements, including disparaging remarks about women, Mexican immigrants and Muslims.
In a foreign policy speech in San Diego, California, on Thursday, Clinton called Trump an unstable person who is too "dangerous" and “unfit" to be president.
"Donald Trump's ideas aren't just different -- they are dangerously incoherent," Clinton said. "They're not even really ideas -- just a series of bizarre rants, personal feuds, and outright lies."
"He's not just unprepared -- he's temperamentally unfit to hold an office that requires knowledge, stability and immense responsibility," she continued.
