Obama's Relatives-nagging questions?

Nagging questions that beg for plausible answers:

Why is it Obama's Kenyan relatives keep showing up in the United States as illegal immigrants? What is that all about? How did they get here? How is it they fly under the radar until they are arrested for a local violation, like DWI? Why is it Barrack is silent? Why is the mainstream news media not on top of this? How many more are there we don't yet know about?
