It's a brand new season of CNN 10! And today, we're learning all about political conventions in the US. One of which is happening today in Chicago, Illinois. We'll also head to Florida where the hunt is on for the Burmese Python. And in Paris, we're talking with Olympic gymnast Simone Biles. All that and a groundhog in a claw machine on today's episode of CNN 10. We're glad to have you back!
