What Did Obama Know About Obamacare and NSA Issues?

How much is our president in the loop on these matters?

When it comes to leadership and personal responsibility, President Barack Obama has made his stance very clear: "The buck stops with me."

It's a phrase he's echoed countless times in the past. But now, he's dealing with an accountability double-whammy -- fallout from the botched Obamacare website and global fury over the wiretapping of some allied leaders' conversations.

So what all did the President know, and when did he find out? Depends on who you ask.
