GREENSBORO, N.C. -- With the jury at the John Edwards trial set to begin deliberations for a seventh day on Tuesday, speculation grows that the 12 people charged with deciding the fate of the former presidential candidate may be deadlocked. Edwards faces six felony charges in a case involving nearly $1 million provided by two wealthy political donors to help hide the Democrat's pregnant mistress as he sought the White House in 2008. To determine Edwards' guilt or innocence, the jury must sift through notes from 17 days of testimony and review about 500 trial exhibits, many of them voluminous phone and financial records.
