Hillary Clinton 'Hard Choices' book tour kicks off

CHICAGO (WLS) -- An enthusiastic crowd welcomed Hillary Clinton Tuesday morning at a Manhattan Barnes and Noble during the first stop on her book tour for her new memoir, "Hard Choices.," before the former Secretary of State was interviewed by Robin Roberts for "Good Morning America."

Clinton is now in Chicago for a two-day visit beginning Tuesday evening when she speaks at a meeting of the Food Marketing Institute and United Fresh Produce Association. She will promote her book on Wednesday at an event with Mayor Rahm Emanuel.

The book and corresponding tour are fueling speculation about whether she will run for president in 2016. She's dropped several hints that she is considering a run, but says she remains undecided.

"The two most important questions are not will you run or can you win," she said. "They are what is your vision for the future of our country and can you lead us there."

At McCormick place, Clinton spoke about the challenges that those in the food industry are facing now.

"How do you feed your children right when they are surrounded by so many unhealthy, bad options?" she asked the crowd. "How do we make sure they get the support and the nurturing they need?"

She also shared that she can't wait to be a grandmother. Daughter Chelsea is expecting a baby this fall.
