Trump had just returned from Saudi Arabia. He sent out a tweet at midnight (daytime there) saying, "Despite the constant negative press covfefe." Until that night, typing covfefe into google translate produced the translation "I will stand (up)" because covfefe is a poor transliteration of cov'fe fe (or something close to that. To make Trump appear stupid, google translate was updated overnight to give a shrug emoji as the result instead. The next morning, Trump deleted the covfefe tweet, then tweeted "Who can figure out the true meaning of covfefe??? Enjoy!"

The entire transaction highlighted the realtime information war that we are still fighting today. He who controls the information controls the narrative.

A month or so later, a Democrat introduced a bill to preserve presidential communications (prevent deleted tweets) called Communications Over Various Feeds Electronically for Engagement Act. This was, most obviously, to mock Trump, and the proposed act went nowhere in congress.
