offered a pointed reminder according to two people with knowledge of their comments, they needed to make sure mister biden did not embarrass himself or damage obama s legacy during the campaign. it seems the former president is worried about joe biden and doesn t have confidence in this. there is no way to take it other than that. it sounds like president obama is worried he may see something or do something that embarrass the obama biden legacy and as we have seen the last couple weeks with all this coming out about hunter biden it is not looking good for biden, and that translate not well to president obama.
