Bill Clinton’s former CIA chief, James Woolsey, will act as an adviser to Republican presidential nominee Donald Trump’s campaign. 

Woolsey, who served as director of the CIA from 1993 to 1995 and describes himself as a life-long Democrat, praised Trump’s commitment to ending defense budget cuts from sequestration. 

He said he can’t support Democratic presidential nominee Hillary Clinton because of the controversy surrounding her use of a private email server as secretary of State. 

“She demonstrated a complete lack of understanding and an inability to lead the agency she headed in such a way as to maintain its mission and security," Woolsey said in a statement. 

“Based on the emails thus far released we know that Secretary Clinton also lacks the ability to lead her senior managers while complying with and maintaining the basic protocols designed to protect our government’s sensitive and classified information. Mr. Trump understands the magnitude of the threats we face and is holding his cards close to the vest.”
