Whistleblower Edward Snowden said Wednesday that he searched CIA and NSA databases for evidence that the US government was hiding aliens — but found no evidence of extraterrestrials.

Snowden made the admission while speaking on Joe Rogan’s podcast, telling the host that if the US is indeed shielding evidence of alien life, the government has hidden it especially well.

“If we are hiding them — I had ridiculous access to the networks of the NSA, CIA, military, all these groups — I couldn’t find anything,” he said.

“If it’s hidden, and it could be hidden, it’s hidden really damn well even from people on the inside,” Snowden added.

During the wide-ranging interview, Snowden touched on a variety of other subjects, including mass surveillance under the Obama administration.

The whistleblower — who leaked tens of thousands of files about surveillance in the US during Obama’s presidency — said he believed the practice worsened during his administration.

“Maybe Barack Obama honestly did want to get to this later, but what we can say today is for all the good that may have been done in that White House, this is an issue where the president went through two full terms and did not fix the problem, but in fact made it worse,” he said in the interview.
