The death of Robert Novak has led many to remember the career of the expert political journalist. Some noted his conversion to Catholicism later in life, with one former colleague calling it his “most important” change of heart. Novak died of a malignant tumor at his Washington, D.C. home on Tuesday. One half of the Evans-Novak “Inside Report,” begun in 1963 with journalist Robert Evans, Novak was known for his ability to explain the feuds and factions of American politics with the help of his many inside sources. For a long time he was co-host of the CNN debate show “Crossfire.”
