Jon Stewart will make another on-air appearance on CBS' "Late Show with Stephen Colbert," part of a growing frenzy of activity by TV's late night programs around the coming Democratic and Republican conventions.
Stewart is expected to be involved with the show's Monday broadcast in some fashion, according to people familiar with the situation, though his screen time will not be significant. This would mark Stewart's second appearance on Colbert's program. He also turned up briefly in the opening segment of Colbert's debut episode. Stewart is an executive producer on the late-night series.
