Hillary Clinton took her criticisms of Donald Trump a step further today as Republicans began their convention in Cleveland.

Clinton regularly calls her opponent 'dangerous' in speeches. Today she told PBS and CBS' Charlie Rose she believes Trump is the 'most dangerous' person to ever run for president.

'No self-discipline, no self-control, no sense of history, no understanding of the limits of the kind of power that any President should impose upon himself. He has shown none of that,' she said.

Hillary Clinton told CBS' Charlie Rose she believes Donald Trump is the 'most dangerous' person to ever run for president

Trump wants to bring back torture, she said, and would 'order the American military to commit war crimes.'

'What he has laid out is the most dangerous, reckless approach to being President than I think we've ever seen.'

A slightly taken about Rose asked the presumptive Democratic nominee if she really meant to say Trump is the 'most dangerous man ever to run for President of the United States?'

Clinton told him, 'I believe that.'

The former secretary of state was also in Ohio today, speaking at the NAACP convention that Trump skipped and at an organizing event of her own.

She's barely up over Trump in the polls in the Buckeye State despite having made four separate visits over the last month.

How is it that Trump - 'a man you just described in such harsh terms' - is running so close to you in the polls, Rose asked her.

'Well, our presidential elections are close and the campaign is really just starting,' she first said.

Clinton added, 'There is a lot of fear in our country. And when Americans are worried they're looking for answers. He's providing simplistic, easy answers.'

'No self-discipline, no self-control, no sense of history, no understanding of the limits of the kind of power that any President should impose upon himself. He has shown none of that,' she said

Perhaps, Rose suggested, she's struggling in the polls because Americans do not trust her. A majority of voters say in almost ever poll that's taken that they are not convinced of her honesty.

'It is something that clearly I don't like to hear,' the former secretary of state who was just cleared by the Justice Department in her email scandal told him. 'Nobody would.'

She likewise noted that the perception those Americans have of her now 'is at such variance with the way I am perceived when I'm doing a job' like when she was in the Obama administration and high approval ratings.

'Part of it is seeking this job at this time of fear, anxiety, discouragement, rejectionism, that is, unfortunately, part of our political environment right now,' she said.

Clinton told him in the clip that aired Monday night on CBS, 'I understand people who are asking these questions.
