That’s not the point. The killer’s family has connections with the Obama government. Obama is attacking the NRA, republicans, etc, and democrats are saying the attack was not Islamic terror in order to deflect from what they know is a scandal because this White House welcomed the radical father. I have no idea how the agents are conducting the investigation, but if it leads to the father then Obama will need to do something to further divert attention and cover this up. He’s already doing that.
What you describe vaguely as “connections” seem to amount to little more than a few brief courtesy meetings. They do not make a case for a conspiracy.
