Picture: AP. A “Saturday Night Live” writer has been suspended indefinitely after tweeting a poorly received joke about Donald Trump’s 10-year-old youngest son, Barron.

A person familiar with the situation but not authorised to speak publicly told The Associated Press that Katie Rich was suspended immediately after writing an offensive tweet about the child.

Rich later deleted the tweet, deactivated her account but then reactivated it Monday, saying she wanted to “Sincerely apologise” for the “Insensitive” tweet and “Deeply regret” her actions.

Barron found support from Chelsea Clinton, with the former first daughter saying he “Deserves the chance every child does – to be a kid.”

Actors Kate McKinnon and Alec Baldwin portray Republican campaign manager, Kellyanne Conway, and Donald Trump, during a skit on Saturday Night Live.

The current controversy over Barron Trump comes as President Trump has lashed out at the way “Saturday Night Live” has lampooned him, with the president saying Alec Baldwin’s semi-regular portrayal of him “Stinks” and calling one of the skits a “Hit job.”
