"I think again we're way out of balance. I think that we've got to rein in what has become an almost article of faith that anybody can have a gun anywhere, anytime," Clinton said. "And I don't believe that is in the best interest of the vast majority of people. And I think you can say that and still support the right of people to own guns."
The Democratic-controlled Senate voted against legislation pushed by President Barack Obama last year that would have expanded background checks for firearm purchases to gun shows and online sales. The legislation came in the aftermath of the deadly Sandy Hook elementary school shootings in Connecticut.
If Clinton runs for president, her views on gun control would clash with Republicans, who have largely opposed efforts to tighten gun laws. During a recent National Rifle Association conference in Indianapolis, for example, GOP Gov. Bobby Jindal of Louisiana, a potential 2016 candidate, said Clinton and Vice President Joe Biden considered the Second Amendment to be little more than "a phrase from a speech writer."
Clinton told attendees at the mental health conference that "at the rate we're going, we're going to have so many people with guns everywhere, fully licensed, fully validated" in settings like movie theaters where shootings have arisen over seemingly mundane things like loud gum chewing or cellphone use.
"That's what happens in the countries I've visited where there is no rule of law and no self-control and that is something that we cannot just let go without paying attention," she said.
During a question-and-answer session, Clinton was asked about the 1993 suicide of Clinton White House lawyer Vince Foster. Referring to him as "our friend in the White House," she said he had been depressed and "filled with anxieties." Like other men she has known who killed themselves, Clinton said, "they did not want to be seen as weak, they didn't want to admit their problems."
Her appearance coincided with the release by Vanity Fair magazine of excerpts from an article by Monica Lewinsky, who as a White House intern had an affair with Clinton's husband when he was president. The subject of Bill Clinton's affair with Lewinsky did not arise during Hillary Clinton's appearance at the mental health summit or at an early childhood education event later Tuesday at the Inter-American Development Bank.
Clinton said she was still considering her political future, telling the Maryland audience she is someone "who has to really mull things over."
"So stay tuned," Clinton said. "When I know, you'll know."
