Roger Stone, an unofficial adviser to President Donald Trump, lashed out at former Director of National Intelligence James Clapper for expressing concern that the president's mental state could lead to nuclear war.
In a tweet over the weekend, Stone shared an interview with Clapper from August 2016.
"I really question his ability, his fitness to be in this office and I also am beginning to wonder about his motivation for it," Clapper told CNN at the time. "Again, having some understanding of the levers that a president can exercise, I worry about, frankly, you know, the access to the nuclear codes."
It was not immediately clear if Stone was aware that the interview is over a year old, but the tweet comes just after Trump suggested that he would take significant military action against a foreign power in the near future.
