Trump has longstanding history of calling elections 'rigged' if he doesn’t like the results

Trump also previously called for the American people, presumably those who didn't vote for Obama, to "fight like hell and stop this great and disgusting injustice," because "the world is laughing at us."

Trump first challenged the election results in 2012, continued to do so in 2016 and has now done it again in 2020.

When he ran to become the Republican Party nominee in 2016, he attempted to cast doubt on the election process. Trump said he did not lose the Iowa caucuses in 2016 to then candidate Sen. Ted Cruz, because he "stole it."
