Trump told The Wall Street Journal on Wednesday that he considers Brennan and other former intelligence officials whose clearances he's considering revoking among the leaders of the investigation.

“I call it the rigged witch hunt, [it] is a sham. And these people led it!” Trump told the newspaper hours after it was announced Brennan's clearance was being revoked.

“So I think it’s something that had to be done," he added.

Brennan served as CIA director under former President Obama, and was one of the officials who briefed Trump prior to his inauguration on evidence of Russian interference.

White House press secretary Sarah Huckabee Sanders read a statement from Trump during Wednesday's press briefing that listed several other Obama-era intelligence officials whose clearances are under review.

“I don’t trust many of those people on that list,” Trump told the Journal. “I think that they’re very duplicitous. I think they’re not good people.”

"Clearly, I think Mr. Trump is getting more and more concerned, more and more desperate, more and more frightened,” Brennan said on MSNBC.

Trump's decision to revoke Brennan's clearance was seen by many as an effort to hit back at one of the most vocal critics of his administration.

The stated reason for revoking Brennan's clearance was that the former CIA director was leveraging his status as a former government official to make “unfounded and outrageous” charges about the Trump administration.

“Mr. Brennan’s lying and recent conduct characterized by increasingly frenzied commentary is wholly inconsistent with access to the nation’s most closely held secrets and facilities, the very aim of our adversaries, which is to sow division and chaos,” Trump said in the statement read by Sanders.

Brennan regularly tears into Trump on Twitter, suggesting he lacks the decency to be president. He notably amounted Trump's meeting with Russian President Vladimir Putin last month to treason.
