Washington (CNN) Former Director of National Intelligence James Clapper said Tuesday that the former intelligence chiefs and national security officials from whom President Donald Trump is considering revoking security clearances are being "oppressed."

In an interview with CNN's Dana Bash on "At This Hour," Clapper suggested that he and others are being targeted by the Trump administration as a form of political retribution.

"The bigger issue to me is the jeopardy to First Amendment rights," he said. "That, to me, is the much bigger issue here where we're being suppressed or oppressed because of our outspoken political views or criticism of the current president."

White House press secretary Sarah Sanders told reporters on Monday that the President is weighing the possibility of stripping the security clearances of a half-dozen former officials, arguing that the individuals under scrutiny have "politicized and, in some cases, monetized their public service and security clearances."

The former officials under consideration include Clapper as well as former CIA Director John Brennan, former FBI Director James Comey, former national security adviser Susan Rice, former deputy FBI Director Andrew McCabe and former National Security Agency Director Michael Hayden, according to Sanders.
