The WGA Comes to the Hill

See the video and story below. Why did the writers go to Capitol Hill? Why did members of Congress take part? What does this episode tell us about their constituencies, their Hill style and their home style?

The Washington Post reports:

Usually, the Rayburn Building is the kind of place reserved for all sorts of serious goings-on conducted by sober-looking folks in suits. The people who think they're running the country. Which is to say, it's not too often that you see the likes of Rep. Jan Schakowsky (D-Ill.) donning a ZZ Top-esque beard and proclaiming "solidarity" with the people who really matter -- entertainment types.
