''Saturday Night Live''
In December 2013, Rich was hired to write for Saturday Night Live. She was recommended for the job by SNLcast memberCecily Strong, a friend of Rich's who was her understudy during her time at The Second City. Rich is one of four writers who work exclusively on SNLs Weekend Update segment. On January 20, 2017, following President Donald Trump's inauguration, Rich tweeted about Trump's youngest son, 10-year old Barron, saying he "will be this country's first homeschool shooter." NBC quickly suspended Rich and had her name deleted from the Saturday Night Live closing credits. After widespread criticism, Rich deleted the tweet and deactivated her account, reactivating it on January 23 with an apology for what she called her "insensitive" and "inexcusable" comments. On January 26, 2017, Trump responded to Rich's tweet by calling Rich "terrible" and saying, "For them to attack, for NBC to attack my 10-year-old son... It’s a disgrace." As of August 10, 2017, Rich had returned to SNL, credited as one of the writers on the SNL spinoff Weekend Update: Summer Edition.
