WASHINGTON (CNN) -

As Hillary Clinton eyes a potential 2016 presidential run, she will speak to a key constituency next month: women.

The former secretary of state is addressing the Women's Leadership Forum 21st Annual National Issues Conference on September 19 in Washington, CNN has learned.

The fundraiser, to be hosted by the Democratic National Committee, will feature President Barack Obama as the keynote speaker.

He will address the forum shortly after Clinton is slated to speak.

First lady Michelle Obama will speak on September 18 at a welcome reception for the two-day event.

The conference will also feature a number of other notable Democratic women, including Planned Parenthood's Cecile Richards, Stephanie Schriock of Emily's List, Neera Tanden of Center for American Progress, New York Sen. Kirsten Gillibrand and DNC Chair Debbie Wasserman Schultz, according to an invitation obtained by CNN.

Feminist activist and icon Gloria Steinem will appear at the event's concluding dinner.

"Turning out women voters is incredibly important to Democrats heading into November, and the conference will be an important opportunity to highlight the clear choice voters will face in November on the issues most important to women and their families," a source with knowledge of the event told CNN.

Donors for the event are being asked to contribute between $25 -- which buys students access to political training sessions -- and $32,400, the maximum annual donation to the major political party committees.

Among other things, the maximum donation allows an individual to take part in a welcome reception featuring Mrs. Obama, two photo receptions and the concluding dinner.

The conference is one of many closely watched appearances that Clinton -- currently the overwhelming favorite for the Democratic 2016 presidential nomination, if she runs -- will make this fall political season.

Clinton and her husband, former President Bill Clinton, are scheduled to headline the Harkin Steak Fry in Indianola, Iowa, just a few days before the women's event. The steak fry is a rite of passage for Democratic presidential contenders.

Hillary Clinton is also slated to appear at a number of other fundraisers to benefit Democrats running in this midterm election year.
