Former CIA Director John Brennan warned Wednesday that Russia "may have something" on President Trump that they could roll out. Brennan said the "fawning attitude" that Trump has shown for Putin says to him that the president has "something very serious to fear" from the Russians.
"The Russians, I think, have had long experience with Mr. Trump and may have things that they could expose and reveal," Brennan said on MSNBC's Morning Joe.
"Something personal perhaps," co-host Willie Geist said to the former spymaster.
"Perhaps. Perhaps," Brennan answered.
WILLIE GEIST, MORNING JOE: What do you chalk it up to? Why won't the president confront Vladimir Putin? Why won't he read the cards and say the things that you say need to be said to Vladimir Putin? Do you believe he is somehow in debt to the president of Russia?
JOHN BRENNAN, FMR. CIA DIRECTOR: I think he is afraid of the president of Russia.
BRENNAN: Well, I think one can speculate as to why. That the Russians may have something on him personally that they could always roll out and make his life more difficult. Clearly, I think it's important for us to be able to improve relations with Russia, but the fact that he has had this fawning attitude toward Mr. Putin, has not said anything negative about him, I think continues to say to me that he does have something to fear and something very serious to fear.
GEIST: You believe Russia has something on him?
BRENNAN: I believe that the Russians would not -- they would opt for things to do if they believe that it was in their interest and the Russians, I think, have had long experience with Mr. Trump and may have things that they could expose and reveal.
GEIST: Something personal perhaps.
BRENNAN: Perhaps. Perhaps.
