Yes, highly controversial and the scandal it's still infamous on every media and press.
Mediatic in my language (and almost by extension it could in English by adapting Romance roots) means something widespread in media but as highly broadcasted over and over because of being scandalous/controversial.
Neither it was "liderar" and "líder" in Spanish (líder from Eng leader, and liderar is 'to lead') about just 100 years ago, and that word almost looks like has been in Spanish forever...
