Donald Trump has slammed Alec Baldwin, the actor who has famously played the US President on NBC's "Saturday Night Live" (SNL) since 2016, saying that watching his impersonation acts were an "agony" for audiences, the media reported. "Alec Baldwin, whose dying mediocre career was saved by his terrible impersonation of me on SNL, now says playing me was agony. Alec, it was agony for those who were forced to watch," Trump tweeted on Friday, at first mis-spelling Baldwin's name as "Alex" before fixing it.
