This isn't the actor's first time stepping away from Twitter due to a controversy. In 2017, Alec announced that he would be taking a break from the social media platform due to some controversial statements he made regarding Harvey Weinstein's harassment and sexual assault allegations (via PBS News Hour). His comments turned heads as he seemed to imply that victims of sexual assault that take financial payoffs are "setting back the course of change (via The Hollywood Reporter)."
In response to the backlash at the time, Alec tweeted, "It is with some degree of sadness that I will suspend posting on this a TWITTER account for a period of [time] and in the current climate." He paired the announcement with an apology in which he claims he never intended to "blame the victim."
Over the years, Alec Baldwin has made his political views very clear via his Twitter account, often retweeting content from left-leaning sources and openly expressing his opinions. And if there was any question of his political leanings, his literal re-enactment and parody of Donald Trump on SNL surely provided a pretty big clue.
