Maybe you're too young to remember? But there are plenty of articles from 2012 still up on the web that discuss Trump's rant calling for a revolution over the results of the "phoney electoral college", for example:

- Trump ranted on Twitter when it became clear Obama would win election
- Later deleted tweet calling for a revolution
- NBC's Brian Williams lashed out against Trump on air, saying he had 'driven well past the last exit to relevance'
- Trump then attacked Williams and his 'boring' newscasts
