CBS announced Thursday that Colbert will replace Letterman when he retires next year after three decades in late night. Though Colbert has appeared on the “Late Show” before, this will be his first time joining Letterman since the announcement.
Letterman, who has endorsed Colbert as his successor, announced his retirement on the show’s April 3 broadcast.
Last week, Colbert praised Letterman without breaking from his buffoonish “Colbert Report” character. He said whoever replaces him will have a big job ahead.
“I do not envy who they put in that chair,” he said.
