Close, Tim....got it, it was Don Ohlmeyer,and, for what it's worth, here are some comments from Wikipedia:
On Saturday Night Live Macdonald most notably anchored the segment Weekend Update. Chevy Chase, the first anchor of WU, has opined that Macdonald is the only anchor since Chevy's tenure to have "done it right." .[1] Macdonald used a deadpan style during the segment, which included repeated references to prison rape, 'crack whores' and the Germans with their love of Baywatch star David Hasselhoff. He also commonly and inexplicably used Frank Stallone as a non sequitur punchline. Macdonald would repeatedly noodle public figures such as Michael Jackson and O.J. Simpson. Throughout the Simpson trial, Macdonald would constantly pillory the former football star, saying Simpson was guilty of the brutal slaying of his wife Nicole. In the broadcast following Simpson's acquittal, Macdonald opened Weekend Update by saying: "Well, it's official: murder is legal in the state of California." He also continued to denounce Simpson after the trial.
Another uncomfortable moment occurred during the April 12, 1997 show when, during a Weekend Update story about Tabitha Soren, he caught a frog in his throat in the middle of a sentence and, live on the air, muttered, "What the **** was that?" The audience applauded, and Macdonald laughed the error away. At one point, he called it his "farewell performance" and, in closing, said, "Maybe I'll see you next week." NBC only received three complaints about the gaffe, and Macdonald was not punished.
Macdonald's time with Saturday Night Live effectively ended in late 1997 when he was fired from the Weekend Update segment upon the insistence of NBC West Coast Executive Don Ohlmeyer, who pressured the producers to remove him, explaining that Macdonald was "not funny." Some believe that Don Ohlmeyer's friendship with O.J. Simpson — a celebrity whom Macdonald often antagonized on the show — may have fueled Ohlmeyer's decision.[1] Ohlmeyer denied the rumor, arguing that other NBC late-night comedians (e.g., Jay Leno, Conan O'Brien, and other SNL players) also constantly lampooned Simpson with little to no sanction, and that his decision was based solely on audience reaction through tapes he had personally reviewed. Despite the incident, Macdonald left the show the following year under decent terms with Ohlmeyer, who originally pushed for producer Lorne Michaels to give Macdonald a shot at the Weekend Update desk in 1994. On February 28, 1998, his last appearance on SNL occurred as host of a fictitious TV show called Who's More Grizzled?, who asked questions of "mountain men" played by that night's host Garth Brooks and special guest Robert Duvall. In the sketch, Brooks' character said to Macdonald's character, "I don't much care for you," to which Macdonald replied, "A lot of people don't."
====================================
And now back to me again. I also saw the first Weekend Update with Norm's successor, Colin Quinn, and this is what Wikipedia has to say about that:
After Macdonald left SNL, his successor, Colin Quinn, gave a short prologue in his first day anchoring Weekend Update, during which Quinn mentioned that Macdonald had shown him "the ropes" of the segment. Quinn then asked the audience if they ever went to their favorite pub seeking their favorite bartender -- and found him to be replaced by a less qualified man named "Steve". After a brief pause, Quinn deadpanned, "Well I'm Steve." Castmember Will Ferrell then appeared as Chicago Cubs announcer Harry Caray, who repeatedly referred to Quinn as "Norm", adding, "Norm, have you gained some weight?"
