Hillary Rodham Clinton will return to Yale Law School in October to address alumni and accept an "Award of Merit" on the 40th anniversary of her graduation.

Clinton, a former secretary of state and potential 2016 Democratic presidential candidate, plans to attend the "alumni weekend" and speak on Oct. 5 at Yale's Woolsey Hall, according to the school's Web site. The weekend's theme is "Global Constitutionalism," although it is not clear what Clinton will discuss in her remarks.

Clinton and her husband, former President Bill Clinton, met on Yale's campus in New Haven, Conn., and graduated from the prestigious law school in 1973. Bill Clinton addressed Yale Law School alumni in 2008, marking the 35th anniversary of their graduation with a speech about "Our Global Challenges."

The Yale Daily News first reported news of Hillary Clinton's visit early Sunday.

Alumni from all classes of Yale Law School have been invited, and Clinton is likely to have an audience of hundreds and potentially thousands of prominent lawyers, policy makers and other intellectuals.

Clinton is in the midst of delivering a series of major policy addresses -- her first was on voting rights last week in San Francisco -- although it was not immediately clear whether she would make her Yale remarks part of the series. She will next address issues of national security and transparency at the National Constitution Center in Philadelphia on Sept. 10. She also plans to speak on America's global leadership and moral authority, but has not yet announced a time or place.

Clinton has long maintained ties to Yale. In 2001, she gave Yale's version of the commencement address as the "Class Day" speaker. When President Obama named her secretary of state, Clinton tapped Harold Hongju Koh, then the dean of Yale Law School, to be her top legal adviser at the State Department. And in 2009, Clinton returned to campus to receive an honorary degree at the university's commencement ceremonies.
