Joe Biden revealed in an interview to CNN that President Barack Obama offered him financial assistance when Biden was determining how to support the family of his late son Beau. As Beau's health declined prior to his passing, he faced the prospect of resigning as Delaware's attorney general.

In order to financially help Beau and his family, Biden and his wife Jill were considering selling their own house in Wilmington, Delaware. But Obama wouldn't hear of it. Just as Biden has Obama's back in office, Obama has Biden's back in real life:

He said, 'I'll give you the money. Whatever you need, I'll give you the money. Don't, Joe—promise me. Promise me.' I said, 'I don't think we're going to have to anyway.' He said, 'promise me.'
