Referring to Gabbard specifically Bolton added: "Given the Russian propaganda that she has espoused over the past period of time, I think she's a serious threat to our national security."
Bolton was asked what message he thought Trump was sending to Beijing with the appointments by anchor Blake Burman.
He replied: "With his announcement of Tulsi Gabbard to be the Director of National Intelligence, he's sending a signal that we have lost our mind when it comes to collecting intelligence.
"Up until a few hours ago, I would have said that was the worst cabinet appointment in recent American history. Of course, since Matt Gaetz's nomination, he clearly has taken the lead on that score."
