Right now I would probably just state your case. Your wife probably knows it as well. Make it about the behavior. Let your wife decide so it's her decision.
"I don't think it's wise to have friends in our lives that don't support marriage and have our best interests at heart. I think trust is important for us going forward and some people I don't trust around my wife. How do you feel about that?"
Find your message and deliver it. It's OK to think and feel that way. Be willing to listen in return, have a dialouge. If it's a showstopper think thru it, understand why and articulate it calmly.
