They got away with targeting conservatives and conservative groups, so there's no reason for them to fear a Congressional investigation. They did get their budget cut, but they've turned it around and made things harder for the public. I would be ashamed to be a Congressman after being punked like they were by Lois Lerner and John Koskinen. I seriously hoped to see someone wipe the smirk off of his face during the hearings, but it didn't happen. Unfortunately, the GOP hates the Tea Party worse than they hate Democrats, so they only gave a token punishment for what was clearly Unconstitutional activity. I don't know if it's legal or not, but it should be a law that any federal employee invoking the Fifth amendment should immediately be terminated and lose their pension.
