ABC News completely ignored the Monday death of heiress Rachel "Bunny" Mellon, who used her wealth to help conceal the mistress of former Democratic presidential candidate John Edwards. CBS and NBC both noted the passing of the 103-year-old and her connection to Edwards, but failed identify Edwards as a Democrat.
On Tuesday's CBS This Morning, co-host Norah O'Donnell touted how Mellon "was a horticulturist who redesigned the White House Rose Garden at Jackie Kennedy's invitation." However, when it came to her involvement with Edwards, O'Donnell only vaguely mentioned: "In later years, she gave money to help presidential candidate John Edwards."
