Former Deputy State Department spokesperson Adam Ereli said Monday that revoking the security clearances of multiple top Obama-era officials would "ring alarm bells" in Washington.

White House Press Secretary Sarah Sanders said at Monday's press briefing that President Trump is looking into revoking clearances for former FBI Director James Comey, former Deputy FBI Director Andrew McCabe, former CIA Director John Brennan, former Director of National Intelligence James Clapper, former National Security Adviser Susan Rice and former National Security Agency Director Michael Hayden.

"I think that we're going down a slippery slope," Ereli said. "Who's to decide what's political and what's not political?"

Kentucky Sen. Rand Paul (R) had earlier in the day called for Trump to revoke Brennan's security clearance, questioning whether the former CIA director was “monetizing” his ability to access to information while in his roles at NBC News and MSNBC.

Ereli said that the potential to remove security clearances seems to be a way of lashing out at President Trump's critics.

"Attacking them this way or going after them in this way or slanting the playing field in this way seems to me to set a pretty dangerous precedent," he said.

Ereli also probed why Brennan's scathing tweet criticizing Trumps' meeting with Russia President Vladimir Putin could potentially encourage retaliation from Trump.

Sen. Paul’s concerns come as other congressional Republicans have pushed for Brennan to testify about Russia's role in the 2016 presidential election.
