A biography of Paula Broadwell on the university's website says she received a master's in international security in 2006.
She was a keynote speaker at the 2012 Alumni Symposium on Oct. 26-27, just two weeks before Petraeus resigned from the CIA and his affair with Broadwell was made public.
The Denver Post reports Broadwell also spoke at an Oct. 9 party in Denver honoring female GOP candidates for the Colorado Legislature.
Broadwell studied in DU's Josef Korbel School of International Studies, whose graduates also include Condoleezza Rice, a secretary of state and national security adviser for then-President George W. Bush.
