(CNN)--A new US intelligence report that finds Russia interfered in the 2020 election to help Donald Trump and hurt Joe Biden also underscores a fundamental truth: The gravest threat to US democracy comes from within.

The report, released by Director of National Intelligence Avril Haines, finds that Moscow sought to inject misleading information about Biden into the campaign through officials and others close to Trump.

The real bombshell it contains is not the confidence of the spy agencies that Russia hoped to subvert American democracy. It is that US intelligence experts effectively confirmed that for the second election in a row, Trump acolytes repeatedly used, knowingly or otherwise, misinformation produced by the spies of one of America's most sworn foreign adversaries to try to win a US election.

And given the advantage of hindsight, the latest intelligence assessment is not just an isolated example of incriminating evidence against Russia and its efforts to create chaos and discord within the United States.

For all of the stale US debate about whether Trump and his aides "colluded" with Russia, there are now multiple reports, intelligence assessments and other known details to expose a damning reality: Moscow with its election meddling, Trump acolytes pushing false claims of voter fraud and his GOP supporters in the states now passing voter suppression laws share the same goal -- the denigration of the US democratic system.
