Washington (CNN) - Expect former Secretary of State Hillary Clinton to make a previously unannounced appearance to talk health care reform when President Obama and former President Bill Clinton discuss the issue at the Clinton Global Initiative Tuesday night, according to two Democrats aware planning for the event.
Health care was her signature policy issue as first lady, but as secretary of state she avoided domestic politics. This week will see her address issues closer to home in her new role as one of the nation's most public private citizens and as a possible 2016 candidate in waiting.
The health care appearance is one in a series of events the former secretary of state will participate in during her four days attending CGI's annual gathering in New York City this week.
Wednesday she will be in the same room as potential 2016 rival and good friend, Vice President Joe Biden. That night she'll speak at a CGI Awards ceremony where the vice president is delivering an award to Mayor Michael Bloomberg, according to a White House official.
In addition she's joining a panel moderated by CNN's Dr. Sanjay Gupta with Melinda Gates and Queen Rania of Jordan. Then she'll announce several commitments related to women and girls. According to the sources, she'll unveil a commitment on wildlife conservation to save Africa's elephants. And she'll also announce support for the Global Alliance for Clean Cookstoves - an effort she championed at the State Department.
CGI falls the same week as the UN General Assembly and as secretary of state she used to spend these weeks across town at the UN, making a brief policy address to her husband's gathering. This week she'll also be a full participant at the Bill, Hillary and Chelsea Clinton Foundation.
