NBC News had to scrap plans for Lester Holt to anchor Nightly News live from Hawaii tonight, on the 75th anniversary of the Pearl Harbor attack. In a Facebook post, Holt explained “an illness in the family prevents me from being there.”   Tonight’s broadcast still will include reports of survivors attending the anniversary observations there, as well as Holt’s taped interview with former Nightly News anchor Tom Brokaw. “On this solemn anniversary, my thoughts are also with the brave Americans who served and sacrificed on that fateful December 7th morning,” Holt wrote.
