The Late Show With Stephen Colbert is shaking up its writing staff, promoting Ariel Dumas to head writer alongside Jay Katsir.

Additionally, supervising producer Opus Moreschi will take on more responsibilities at the CBS late night show, such as overseeing long-lead projects while remaining part of the writing staff. Katsir, who was already serving as head writer, will also be a supervising producer.

"I have worked with all three of these incredibly talented people since The Colbert Report," said Colbert. "I am thrilled that someone as funny and dedicated as Ariel will be my new head writer and that Opus and Jay will continue to be comedic Gibraltars on which I can lean and host donors from whom I can harvest organs."
