Ok, well, it seems that Cotton has been the source of even weirder things from the House. Apparently others have heard of this, but I didn't before today, so I'm posting it.
http://www.washingtonpost.com/blogs/plum-line/wp/2015/03/11/for-tom-cotton-letter-to-iran-is-anything-but-a-fiasco/"While in the House in 2013, Cotton introduced an amendment to prosecute the relatives of those who violated sanctions on Iran, saying that his proposed penalties of up to 20 years in prison would 'include a spouse and any relative to the third degree,' including 'parents, children, aunts, uncles, nephews, nieces, grandparents, great grandparents, grandkids, great grandkids.' Forget about the fact that the Constitution expressly prohibits 'corruption of blood' penalties — just consider that Cotton wanted to take someone who had violated sanctions and imprison their grandchildren. Needless to say, this deranged piece of legislation was too much even for Republicans to stomach, and it went nowhere."
