Bush in intensive care GOP chairmen say they have deal with Justice on documents MORE says the United States needs to “break down that highest, hardest glass ceiling” of electing a female president. 

"I know I have a decision to make," Clinton told People magazine in a wide-ranging interview published Wednesday. 

“To have a woman president is something I would love to see happen, but I’ll just have to make my own decision about what I think is right for me," Clinton, widely considered the frontrunner for the Democratic nomination, told CNN.

Clinton also discussed becoming a grandmother, and whether that would change her calculus. Her daughter Chelsea is expecting her first child this fall.

“With the extra added joy of 'I'm about to become a grandmother,' I want to live in the moment. At the same time I am concerned about what I see happening in the country and in the world,” she said. 

Clinton’s interview, which will appear in People's issue hitting newsstands Friday, comes right before she embarks on a national tour promoting her new book Hard Choices about her experience in the Obama administration.

She is also slated to sit down for a number of media interviews including with ABC News, Fox News and a televised town hall on CNN.

Clinton said she hasn't read an essay by Monica Lewinsky in Vanity Fair that brought her husband President Bill Clinton's trial for impeachment back into the public eye.

Hillary Clinton said “everybody needs to look to the future” instead of looking back at that part of her husband’s presidency. “I’ve moved on,” she said. 

The interview had a few lighter notes. 

After receiving criticism over the years for her evolving hairstyle, she was asked what her hair strategy will be for 2016. 

"I’m at an age where I can pretty much do what I want: Here I am, whether you like my hair or not,” she said.

Before Clinton left public life last year after serving as secretary of State, she expressed excitement over the ability to sleep later. 

"Oh, my gosh. I slept in to probably 8 o'clock," she told People with a chuckle. "That's good, huh?"
