@coldjoint,
The trump pre-election team(and post election) had questionable contacts with unsavory and outright unfriendly governments/people which came to light on surveillance of those people, as our intelligence people should have done, not surveilling the trumpies whjo made the contacts. Once theyi contacted the unsavories, they became fair game themselves. Trump was the slug who put the slugs on his team. It's on him, not Obama.
