The foreman from the 2004 trial, a Chicago man, testified he received ominous text messages after William White posted his personal information on a website.
Defense attorneys noted White never directly threatened the foreman.
In court Tuesday, an FBI agent testified that White once posted similar information about a columnist with the Miami Herald newspaper.
Hale is currently serving a 40-year sentence for ordering the head of his security to kill Judge Joan Lefkow.
