In both classified and public reports, U.S. intelligence agencies have said Russian President Vladimir Putin ordered actions to interfere with the election. Those actions included the cyber-theft of private data, the placement of propaganda against particular candidates, and an overall effort to undermine public faith in the U.S. democratic process.

Members of Congress, both Democrats and Republicans, have held open and closed door hearings to probe Russia’s actions. The congressional investigations are ongoing.

Facebook, Google and Twitter have investigated their own networks, and their executives have concluded — in some cases after initial foot-dragging — that Russia used the online platforms in attempts to influence the election.

After all this, one man keeps saying it didn’t even happen.
