Tillerson to CNN: I Never Doubted Trump's Mental Fitness

Secretary of State Rex Tillerson declared Friday he had never had any reason to question President Donald Trump's mental fitness and intends to continue in office.

Tillerson's comments came in an interview to CNN in the aftermath of a bombshell book that cited White House aides questioning the president's ability to serve.

"I've never questioned his mental fitness, I've had no reason to question his mental fitness," Tillerson said.
