Ever since Trevor Noah left as host of The Daily Show, the show has been having a series of guest hosts, seemingly trying out people to see who might fit the bill best. The results must have been unsatisfactory because they have brought back former long-time host Jon Stewart, the person who made it much more focused on sharp political and social satire until he retired from the show nine years ago. He will host the show only on Mondays, though, with the correspondents doing the next three days of the week.
In his first appearance, Stewart did an extended piece on the absurd lack of reasonable gun control measures in the US. (I am informed by commenters Bruce and johnson catman that this is an old clip that they see-released on the TDS website. His first appearance will be this coming Monday.)
