I doubt they even bothered to explain it to him. His wife tweets these “clarifications” without his knowledge.
I doubt they’d even trust that to Dr. Jill.
If you watch her recent interviews, she isn’t exactly the brightest light on the Christmas tree, either - often, to me, she has seemed very reluctant and uncommitted to this whole enterprise.
They’ve got some political-hack ‘fixers’ handling him and bandaging his mistakes.
I sure hope they’ve promised the Mrs./Dr. Biden something really big.
