Former CIA Director R. James Woolsey Jr. resigned from President-elect Donald Trump’s transition team Thursday reportedly because of tensions over Trump’s plan for U.S. intelligence agencies. “Effective immediately, Ambassador Woolsey is no longer a senior adviser 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. The Washington Post reports Woolsey felt he’d been excluded from discussions on intelligence matters with Trump and retired Lt. General Michael Flynn, who is set to be his national security adviser. Woolsey has been involved with four presidential administrations.
