In a TV interview he was full of praise for the former Secretary of State
Donald Trump has once again been left red faced by comments caught on camera several years ago - this time relating to his rival Hillary Clinton.
The US presidential campaign has been defined by a relentless nastiness never seen before in a race for the White House.
Mrs Clinton has described Mr Trump as "the most dangerous person to run for president in the modern history of America".
For his part, the Republican nominee can barely say Mrs Clinton's name without prefacing it with the allegation that she is "crooked".
Among a cascade of insults fired at her at campaign rallies and during the presidential debates, he has also famously called her a "nasty woman", proving there is absolutely no love lost between the bitter rivals.
But a newly unearthed video proves that Mr Trump - who had both Bill and Hillary Clinton as guests at his 2005 wedding to Melania - was once rather more fond of his rival.
In a TV interview with NY1 News from 2008, Mr Trump was full of praise for the former Secretary of State.
"I think that she is a wonderful woman..." he said.
"I think her history is far from being over… I think she is going to go down at a minimum as a great senator. I think she is a great wife to a president."
"You know, Hillary is a very smart woman, very tough woman, that's fine," he added. "But she is also a very nice person. I know Hillary and I know her husband very well, and they are fine people."
He also had some warm words for Bill Clinton, whose record as president, including his alleged infidelity during his time in office, Mr Trump has slammed in recent weeks.
"Bill Clinton was a great president," he said.
"Look at what happened during the Clinton years, we had no war, the economy was doing great, everybody was happy. A lot of people hated him because they were jealous as hell."
On Saturday, Mr Trump set out his plans for his first 100 days in office during a 45-minute speech in Gettysburg.
He vowed to create 25 million jobs over a decade, cut middle-class taxes, and cut illegal immigration.
He also said he would impose Congressional term limits, renegotiate the North American Free Trade Agreement and repeal President Barack Obama's signature health care reform.
With just 17 days left until the presidential election, Donald Trump is trailing in the polls, with a host of recent sexual assault allegations threatening to overshadow his campaign.
The latest woman to come forward is adult film actress Jessica Drake, who claims that in 2006 Mr Trump offered her $10,000 and the use of his private plane to come to his hotel room alone.
She told a Los Angeles press conference he had also kissed her without her consent.
During his Gettysburg speech, the Republican nominee once again labelled his accusers "liars", warning he would sue them once the election is over.
"The events never happened. Never," he said to cheers.
