President Trump says Obama has committed treason: “It would be President Obama. And Biden was there with him ... the leader of the gang was Obama. Barack Hussein Obama. He's guilty. This is treason.”

What the Evidence Shows
The claim that President Obama committed treason, as stated by President Trump, involves allegations that Obama orchestrated a 'treasonous conspiracy' to undermine Trump's 2016 election victory. This assertion is primarily based on political rhetoric and unproven conspiracy theories promoted by Trump and some of his allies, including Tulsi Gabbard, who has called for prosecution over alleged manipulation of intelligence.newsx.comnewsx.comBarack Obama Treason Conspiracy: Will Obama Be Arrested?

However, these claims have not been supported by credible evidence or legal findings. Investigations into the 2016 election interference and related matters have not produced proof of treasonous acts by Obama or Biden. The use of terms like 'leader of the gang' and 'treason' in this context is a political accusation rather than a legally substantiated fact.
Additionally, media outlets with strong editorial standards and fact-checking have characterized these claims as part of a broader pattern of unfounded allegations. The AI-generated videos shared by Trump depicting Obama's arrest are deepfakes and do not represent real events. Overall, the claim conflates political opposition with criminal conduct without meeting the high legal standard required to prove treason under U.S. Law.
