The CIA came to the Trump team, told them foreign agents may try to contact them and use them, and to tell them if they happened...?
Trump's people were ALREADY HAVING multiple high level meetings with Russians including ambassadors, bankers and mafia, and DIDN'T BOTHER TO MENTION IT. What sort of crime do you think that is? Is there even a word for it?
Boris! Hide in the closet! "Russians? We haven't seen any Russian no-sirree!"
I'll help, it's called treason when in connection with a political campaign, and lying to the CIA which they did again and again is illegal in any circumstance.
