Saturday Night Live staffer Katie Rich is no longer working on the show after controversy gathered around a tweet she posted about Donald Trump’s 10-year-old son.

“Barron will be this country’s first homeschool shooter,” she wrote during the inauguration, when a ton of memes were circulating about the boy.

Rich deleted the tweet a few hours later, but Trump supporters were still calling for an apology or dismissal.

SNL hasn’t officially commented on the situation, but a source told Deadline Rich was suspended immediately after the tweet and her suspension is indefinite. She had been writing for SNL for over three years.

An apology tweet did arrive last night, with Rich writing: “I sincerely apologize for the insensitive tweet. I deeply regret my actions & offensive words. It was inexcusable & I'm so sorry.”
