Update, 11/12/12, 10:43 p.m. EST: The third paragraph of this story has been revised to include comment from Chadbourne & Parke’s Abbe Lowell about how he came to represent Jill Kelley.

Chadbourne & Parke white-collar criminal defense heavyweight Abbe Lowell has joined the fray surrounding the resignation of Central Intelligence Agency director David Petraeus, who stepped down Friday in light of the Federal Bureau of Investigation revealing that Petraeus had an extramarital affair with his biographer.

Several news outlets reported Monday
that Lowell is representing Jill Kelley, a 37-year-old Tampa woman who complained that she was receiving threatening emails, which turned out to be from Paula Broadwell, a West Point graduate who chronicled Petraeus’s life in a book published in January that she coauthored. Investigation into the emails led to the discovery of the affair between Petraeus and Broadwell.
