'Inappropriate': An official has claimed that emails exchanged between General John Allen, left, and Jill Kelley, right, who organised military parties in Tampa, Florida, were 'like phone sex over email'
Allen, who has two adult daughters with his wife Kathy, and Kelley, who is married with three children, both deny any wrongdoing, but officials described the messages as 'potentially inappropriate'.
Now two U.S. officials have told Fox News that Allen's messages to Kelley were more than just flirty, with one calling them sexually explicit and the 'equivalent of phone sex over email'.
