He's also warned him to watch what he says in public
Outgoing CIA director John Brennan has lambasted Donald Trump, saying he does not understand Russia's intentions.
Mr Brennan also warned Mr Trump to watch what he said in public and attacked him for comparing the intelligence agencies to Nazi Germany.
He said "Spontaneity is not something that protects national security interests," before adding "And so therefore when he speaks or when he reacts, just make sure he understands that the implications and impact on the United States could be profound."
Speaking to Fox News on Sunday, when asked about the Middle East he said "It's more than just about Mr. Trump. It's about the United States of America."
Trump has reluctantly accepted US intelligence's conclusion that hackers acting on the Russian strongman's authority interfered in the US elections.
He has hinted that he may lift sanctions imposed on Russia over Moscow's alleged cyberattacks if Russia helps the US fight jihadist groups.
Meanwhile, Kelly-Anne Conway, from the incoming administration, recently told US TV Show 'Fox and Friends' - that opponents need to stop trying to discredit Trump and that they should work with the new White House.
