JOHN OLIVER (HOST): The Republican National Convention in Cleveland, the most apocolyptic thing ever to happen in that city, and bear in mind, their river has repeatedly caught fire. [...] But that message of Trump as a skilled manager was somewhat undercut by the fact the entire convention was a mismanaged shitshow. From Melania Trump using a partly plaigiarized speech to Ted Cruz being booed off the stage for not endorsing Donald Trump to the fact that supposedly Donald Trump knew Ted Cruz wouldn't endorse him and didn't care. [...] It's actually fitting that Trump had seemingly done so little to prepare for his party's convention, given that the party itself had done so little to prepare for Donald Trump.
