Here's what's happening today in pop culture — and it's all tied to the just-concluded Democratic National Convention:

• Hillary Clinton, or her writers, showed a lot of pop-culture savvy in her closing convention speech Thursday night — quoting "Hamilton" and referencing Chumbawumba and Lil Wayne. [Playbill, The Huffington Post]

• Republicans are upset at seeing Bradley Cooper — who played their hero, Chris Kyle, in "American Sniper" — is actually a loyal Democrat. [The Daily Beast]

• Katy Perry sang from the convention stage before Hillary Clinton's big speech Thursday night — which shows the difference when you actually get the musician's permission before using their songs. [Vulture]
