Former CIA director R. James Woolsey Jr., a veteran of four presidential administrations and one of the nation’s leading intelligence experts, resigned Thursday from President-elect Donald Trump’s transition team because of growing tensions over Trump’s vision for intelligence agencies.

Woolsey’s resignation as a Trump senior adviser comes amid frustrations over the incoming administration’s national security plans and Trump’s public comments undermining the intelligence community.

“Effective immediately, Ambassador Woolsey is no longer a Senior Advisor to President-Elect Trump or the Transition. He wishes the President-Elect and his Administration great success in their time in office,” Jonathan Franks, a spokesman for Woolsey, said in a statement.

Woolsey suggested in a pair of cable television interviews Thursday evening that he was only an informal adviser to Trump, with duties that included speaking to the journalists about Trump and his national security policies.

Woolsey said on CNN that he did not want to “fly under false colors” any longer. “I’ve been an adviser and felt that I was making a contribution….. But I’m not really functioning as an adviser anymore. When I’m on the [television] screen, everybody announces that I’m a former CIA director and that I’m a Trump adviser and I’m really not anymore.”

“Jim is very uncomfortable being considered an adviser in an area where one might consider him an expert when he is not involved in the discussions,” one person close to Woolsey said. “To be called ‘senior adviser’ and your opinion is not sought is something he cannot handle.”
