In politics, it's strange how some seemingly immovable objects or resolute positions just vanish overnight. Such was the case with "Morning Joe" host Joe Scarborough and his wife and co-host Mika Brzezinski cozying up to their former nemesis right after Trump won the election. 

But such changes are not limited to concern over the future wrath of a newly empowered second-term president. It also appears to be applying to Cabinet nominees such as Robert Kennedy Jr., even when he has not yet been confirmed. Such appears to be the case of The U.S. Food and Drug Administration officially banning the use of red dye No. 3, aka erythrosine.
