Sauce on this is talk radio, 2 or more people put forth this idea:
Farm Bill failed cuz the Freedom Caucus is exercising veto power. They are slamming down Paul Ryan (good thing to do) for NOT bringing forth the conservative immigration bill which would start to fix legal immigration, all but stop illegal immigration AND fund The Wall. They are pushing for Jim Jordan to take over as Speaker NOW. They are saying we will vote against everything until Wall is funded, then we will do the Farm Bill. Imo it is a great move.
