Do you have a source for this? I do like the fact that they are trying to close the loophole before it is implemented but I can find little to back up your claim.
You might try to do your own homework at thomas.loc.gov, where everything is published for all to see.
No, when you cite an alleged fact, you should give the citation.
Presumably you have a citation, if it's a real fact and not something you made up. When you don't provide it, a pretty good guess is that either
(1) it's something you just made up, and hence I shouldn't waste my time to try to track the non-existent fact down with an internet search, or
(2) it was too much trouble for you to do the internet search to find-- and if it was too hard for you to find, being sarcastic about why I won't spend my time finding it is completely hypocritical.
Executive summary: when you cite a fact, it is your burden of proof to provide the citation.
