John Newman, an employee at the newspaper's advertisement department, testified that Ruby became upset over a right-wing anti-Kennedy ad published in the "Morning News", that was signed by "The American Fact-Finding Committee, Bernard Weissman, Chairman". Ruby, who was sensitive to antisemitism, was distressed that an ad attacking the President was signed by a person with a "Jewish name". Early next morning, Ruby, while driving, noticed a political billboard featuring the text "IMPEACH EARL WARREN" in block letters. Ruby's sister Eva testified that Ruby had told her he believed that the anti-Kennedy ad and the anti-Warren sign were connected, and were a plot by a "gentile" to blame the assassination on the Jews.
