“Saturday Night Live” suspended a writer who made fun of Donald Trump’s youngest son on Twitter

Katie Rich is now benched indefinitely from her gig, writing for “Weekend Update,” sources close to the show said Monday.

Rich took to Twitter on Monday to say sorry: “I sincerely apologize for the insensitive tweet. I deeply regret my actions & offensive words. It was inexcusable & I’m so sorry.”

On Friday, the day Trump was sworn in as America’s 45th president, Rich tweeted a tasteless joke about 10-year-old Barron Trump: “Barron will be this country’s first homeschool shooter.”
