Joe Rogan, the suspected white supremacist who just a few months ago suggested he would vote for Sanders, recently indicated on his podcast that he believed Donald Trump‘s baseless and vague charges that Barack Obama somehow broke a law during the transition from his administration to the current one.

He said Obama was “essentially using the FBI to spy on Trump,” a theory that former National Security Adviser Susan Rice debunked on Tuesday.

Trump wants Americans to believe that Obama tied to entrap incoming National Security Adviser Michael Flynn to discredit and possibly invalidate the 2016 election.

But the declassification of an email sent by Rice, Obama’s national security adviser, has effectively undermined Trump’s Obamagate claims.

While Trump has maintained without proof that Obama’s team had the FBI investigate Flynn, Rice’s statement said that the “email clearly states that President Obama stressed that he was ‘not asking about, initiating or instructing anything from a law enforcement perspective.”
