NBC News confirmed Thursday that John Reiss is stepping down as executive producer of NBC Nightly News With Brian Williams effective today (Friday). Although some reports indicated that Reiss was leaving because of friction between him and Williams, the news anchor had nothing but praise for Reiss on his blog, The Daily Nightly, saying that the program on his watch has "enjoyed astounding success." Williams commented, "As schmaltzy as it sounds, he's also been dedicated to all of you: by putting his heart and soul into the best television he could muster from all of us for the past two years." Meanwhile, the TVNewser website said that it had received two tips from NBC insiders that Alex Wallace, the NBC News vice president overseeing the nightly newscast, was in line to replace Reiss. One of the tipsters told the website, "Her only prior experience running a broadcast was Weekend Today." But, he added, "she is very popular with [NBC Universal CEO] Jeff Zucker and [NBC News President] Steve Capus." Meanwhile, NBC also announced Thursday that Kevin Reilly had signed a new deal to remain as president of NBC Entertainment.
