Hillary Clinton's running mate Tim Kaine says untruths the Democrat may have told about her emails can be chalked up to 'variations' in the language she used when answering scores of questions about the scandal.

'If you ask somebody a question 150 times or 200 times, you're gonna be able to find that they don't use exactly the same word every time,' Kaine told NBC's Savannah Guthrie on Today. 'There's gonna be variations, and then people are gonna play on those. '

Clinton has admitted she made a mistake and apologized, he said.

'When has Donald Trump during the course of this campaign or his life said I made a mistake, and I'm better and I'm gonna learn from it.'

Guthrie had noted that at least four times that Clinton made statements to the public that 'turned out' not to be true.

She told him Clinton had used the 'same verbiage' on those occasions, the issue is that what she said 'just happens to not be true.'

'Here's what I've heard her say. I've heard her say, I made a mistake, and I've learned something from it, and I wouldn't do it again, and I apologize.'

Pressing him, Guthrie said Clinton has not, however, acknowledged that she made false statements to the American people.

'The bottom line is this: This is an area where she says, I made a mistake and I've learned from it, and I've improved, and I'm gonna do it differently,' Kaine said.

Clinton says she never sent or received classified information. But the FBI's investigation into her secret server determined that she did receive several items that were labeled classified, although they were not properly marked.

That's a distinction she and her campaign have used in its defense of her behavior - the emails were missing the appropriate classified headings even though they had classified markings inside.

And, the information the messages to Clinton contained was not, in almost every instance, actually classified, they say, pointing to statements from the State Department. It was mistakenly marked that way.

Clinton also testified under oath to Congress that her lawyers turned over all of her work product. They determined which emails were personal and which belonged to the State Department through search terms. But they also read and reviewed each individual email, she claimed.

FBI Director James Comey said her lawyers did not, in fact, look at every email. They relied solely on the search terms, allowing thousands of her emails to slip through the cracks.

Kaine was joined by wife Anne Holton. She said she's not interested in his Senate seat if he becomes vice president

The State Department said Tuesday that it would comply with a lawsuit brought by a conservative watchdog group, Judicial Watch, and turn over the emails discovered by the FBI for public release.

Clinton's email woes became a fresh problem for the Democratic ticket yesterday when the FBI gave copies of its notes from her interview with agents to Congress.

Her campaign told reporters it would prefer that the bureau also make those documents public, all at once. The Democratic presidential candidate's aides do not want them released or leaked in piecemeal, dragging out the saga even longer.

Kaine told Guthrie in the special for Today, 'Anything that the FBI gives to Congress they should give to the public.

'Let the public see what the FBI decides to let Congress see,' the Virginia senator stated.

Clinton and Kaine are beating Republicans Trump and running mate Mike Pence in national surveys by six points on average, according to poll-tracking website Real Clear Politics.

Their odds of winning Colorado and Virginia, Kaine's home state, had them putting ad buys on hold there this month and redistributing the resources elsewhere.

Kaine said they're not getting over confident, though, as some Democrats worry.

'I see no complacency in the team,' he said, positing that it's already been 'a season of surprises.'

As for Clinton's mental and physical stamina, something Trump questioned this week on the trail, Kaine said, 'I have no idea what he's talking about.'

She spent four years as secretary of state traveling around the world, and has put up with the 'grueling nature' of the campaign. Trump, he said, is mentioning her health to 'deflect attention' from his own deficiencies.

Kaine's wife Anne Holton, the former secretary of education for Virginia, joined him for the interview on NBC. She resigned from her post when her husband was tapped to be Clinton's VP.

Holton said it was hard to leave to her job but she's enjoying her time on the campaign trail. The politician's wife also said she has no interest in taking his U.S. Senate seat if he's elected to the White House.
