Would someone kindly explain what the story is here? Kushner is not under investigation of any wrongdoing. The purpose of discussing the comm-channel with the Russians was:

"For Russian military officials to brief Flynn about the Syrian war and to discuss ways to cooperate there. Neither side followed up on it. And less than two weeks later, the idea was dropped."

The proposal was a perfectly sensible one that could lead to closer cooperation in combating the terrorist groups in Syria. Nevertheless it was never followed up on, perhaps because Rex Tillerson didn't want it. Trump haters. What' the problem?
