After eight months defined by partisan gridlock and historically low approval ratings, Congress has headed home for five weeks -- not returning to the nation's capital until the second week of September.

Kentucky Sen. Rand Paul

Over the weekend, we wrote a piece detailing six lessons we learned about Congress -- and its inhabitants -- in the the first eight months of the year.  That got us to thinking about the most memorable moment during that time, the single episode that has defined the 113th Congress so far.

Our pick? Kentucky Sen. Rand Paul's nearly 13-hour long filibuster of the nomination of John Brennan to be the next CIA director. (Make sure you check out the seven most memorable moments from the filibuster.)

Paul's speechifying on drones showed us: (a) he is a power center within the party, (b) filibustering is the new legislating when it comes to GOP politicians building a national reputation among conservatives, and (c) principle is a powerful political message.

So, you know our pick for the most memorable moment of the 113th Congress so far. What's yours? Offer it in the comments section below or tweet it with #fixmoment. We'll try to compile a list of the best nominations later this week. Get to it!
