GOP Senator Grassley now minimizing Valerie Plame leak

Grassley says that he's outraged that no one complains about this program being leaked but they're all upset about Valerie Plame's CIA identity being leaked.

Well, gee, Senator. I can understand how today's breed of Republican, who can't seem to understand why it's important to follow the rule of law, wouldn't understand the difference between outing a CIA agent for personal and political gain, versus outing an illegal program where the US government is spying on American citizens in violation of everything our country stands for. The second case is called whistle-blowing, and it's protected by US law. Why do we have laws on the books protecting something that you now claim is so bad?

I suppose Grassley is also very upset about that leak back in the early 1970s where we had a president breaking into his political opponents' party headquarters. Can we retroactively prosecute Woodward and Bernstein for publishing that terrible leak?
