How is this news?
I'm not asking that rhetorically as a way of saying "this is old news," I mean, what about this story is the least bit newsworthy? Is it at all surprising that Snowden's father would want to visit him? that Russia would give the senior Snowden a tourist visa (as it does for thousands of other Americans every year)? that the Snowdens would want to talk about Edward's legal problems? And why would anyone (other than the Showden family) care?
Edward Snowden is definitely newsworthy. But that doesn't make everything and everything relating to him worth a story.
