This is the second time that Arnett was sent packing from a tv network.
Arnett, who won a Pulitzer Prize for his Associated Press reporting in Vietnam, suffered a major embarrassment in 1998 when he narrated a CNN documentary that had to be retracted over charges that U.S. troops had used nerve gas in that war. Arnett protested that he had contributed "not one comma" to the script, but CNN did not renew his contract the next year. (The last paragraph was taken from the Washington Post website.)
