Trump: "Barack Hussein Obama is the ringleader. Hillary Clinton was right there with him and so was Sleepy Joe Biden, Comey, Clapper. They tried to rig an election and they got caught. And then they did rig the election in 2020. And then because I knew I won that election by a lot, I did it a third time and I won in a landslide."

The claim consists of several interconnected assertions: first, that Barack Obama was the 'ringleader' of an effort to rig elections; second, that Hillary Clinton, Joe Biden, James Comey, and John Clapper were complicit; third, that they tried to rig an election and were caught; fourth, that the 2020 election was rigged; and finally, that Trump won the 2020 election by a large margin and did so a third time. Each of these components has been extensively investigated and adjudicated by multiple authoritative sources.

Regarding the 2016 election, investigations including those by the Department of Justice and bipartisan congressional committees found no evidence that Obama or his administration orchestrated a conspiracy to rig the election. While there were intelligence assessments about Russian interference aimed at influencing the election outcome, no credible evidence supports claims that Obama or Clinton engaged in illegal rigging.foxnews.comfoxnews.comObama officials admitted they had no 'empirical evidence' of Trump-Russia...

On the 2020 election, multiple audits, recounts, and court rulings across states confirmed Joe Biden's victory. Claims of widespread fraud or rigging have been repeatedly debunked by state election officials from both parties and independent observers. Courts dismissed numerous lawsuits for lack of evidence. The assertion that Trump won in a landslide contradicts certified results and official records.

The statement that Trump 'did it a third time' is ambiguous but appears to refer to unsubstantiated claims about subsequent elections or political events without factual basis.

Overall, these claims rely on conspiracy theories and politically motivated narratives rather than verifiable facts. The sources reporting these claims often come from partisan or fringe outlets with vested interests in promoting such narratives.theguardian.comtheguardian.comTulsi Gabbard calls for Obama to be prosecuted over 2016 election claims Credible mainstream media and official investigations do not support these assertions.

Therefore, the claim is demonstrably false based on available evidence and official records.
