Oliver's Emmy-winning "Last Week Tonight" is structured around one main segment each week that dives deep into a particular topic. Recent subjects have included juvenile justice, AI and deferred prosecution agreements. Oliver has also tackled segments focused more on politics, and he has been critical of President Donald Trump.

On July 27, Leno, 75, said at the Ronald Reagan Presidential Foundation & Institute that although he loves political humor, he tried not to turn off half his audience during his years as The Tonight Show ’s host.
