“If I ever mistreated anybody, or made you feel bad, that was not my goal

 “If I ever mistreated anybody, or made you feel bad, that was not my goal,” he said in the meeting, according to a staff member who was present. “I want this show to be fun. It should be inclusive for everybody. It should be funny. It should be the best show, the best people. I just wanted to say I miss you guys.”

NBC released a statement on Thursday saying: “We are incredibly proud of ‘The Tonight Show,’ and providing a respectful working environment is a top priority. As in any workplace, we have had employees raise issues; those have been investigated, and action has been taken where appropriate.”

On Friday, a spokeswoman for NBCUniversal said Mr. Fallon and the show were not under investigation because the allegations in the article were years old and had been addressed by the company.

Rolling Stone reported that during a taping with the comedian Jerry Seinfeld, Mr. Fallon had scolded a staff member holding a cue card. The article went on to report that Mr. Seinfeld had forced Mr. Fallon to apologize to the employee, and that other staff members had described the moment as “uncomfortable.”
