I think Code Monkey’s hypothesis that POTUS flipped Kemp, is a reasonable one. It would explain the all smiles tweet from the White House Christmas party. Maybe having his daughter’s boyfriend killed, as well as maybe other incentives of which we can only speculate, helped to give him a change of mind
I still don’t get all the smiles. One Christmas, cousin’s new husband of a year or so took his own life. Guarantee there weren’t many smiles around the Christmas tree for anybody that year.
