It's fine to try to get along, if that's all it is why all secrecy? We as a country have no idea what he's saying in those meetings and with only a Russian interpreter in the room HE has no idea if he's being told what Putin is saying either. If he didn't hide stuff and lie so much we might be able to believe he's just trying to get along better.
If you want to say you don't trust him, that is your right. To say the act is secrecy is not founded on anything but your distrust. There is nothing about Trumps policies with Russia that indicate he is favoring Russia at the expense of the U S.
