Trump would do well to reassess his appointments. He should select candidates who do not have ties to the Russians. If he does not they will become his Achilles heal. American sentiment is turning against Russia, the US's old nemimis. Anyone seen cozying up to Russia will be suspect. 

Trump can stay out of this issue if he turns against his "friend" Putin. If he does, though, he is buying into the argument that the Russians did interfere with the election and had an impact on the results. This would be a tacit acknowledgement that he did not win the election. The Russians won it.

If he stays loyal to Putin he will run afoul of members of congress and senate AND give them a reason to impeach him.

Nice play, Obama. Trump will look good wearing this.

Do you have any other tricks up your sleeve?
