Former Massachusetts governor and 2012 presidential candidate Mitt Romney said former Secretary of State Hillary Clinton's use of a personal email while at the State Department is an example of "Clintons behaving badly."
In an interview with Yahoo global news anchor Katie Couric, Romney said the controversy over Clinton's emails is "a mess."
"I mean, it's always something with the Clintons. Which is that they have rules which they describe before they get into something, and then they decide they don't have to follow their own rules," Romney said. "That I think is gonna be a real problem for her."
Romney argued Clinton chose not to follow federal guidelines over email.
"She was making policy that represents history for this country, that will shape the relations between our country and other countries. And that's why there are rules and regulations that what she says and what she communicates and what she deliberates should be part of the historical record," Romney said. "But she chose to say, 'No. I'm not gonna follow those rules and regulations. Not only am I gonna have private email, I'm gonna put the server in my house so that there's no way anyone can find out what was really said.' That is something which is going way beyond the pale."
Romney also told Couric a 2016 run is "not happening" for him.
"I don't think there are any reasonable circumstances under which I would be a Republican contender for the White House in 2016. That's just not happening. And we're not proceeding as if it would," Romney said. "My team and my donors and everybody else is working for other candidates, which is the way I'd like to see it."
Romney officially announced he wouldn't be running for president in January.
